The measure of the seventh angle in the heptagon is 125 degrees.
What is Polygon?A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.
We are given the measures of six angles in the heptagon, which are:
95, 107, 132, 138, 145, and 158 degrees
Sum of angles in Heptagon is 900 degrees.
To find the measure of the seventh angle, we can subtract the sum of the six known angles from the sum of all the angles in the heptagon:
Measure of the seventh angle = Sum of angles - Sum of known angles
Measure of the seventh angle = 900 degrees - (95 + 107 + 132 + 138 + 145 + 158) degrees
Measure of the seventh angle = 900 degrees - 775 degrees
Measure of the seventh angle = 125 degrees
Therefore, the measure of the seventh angle in the heptagon is 125 degrees.

of the pyramid is 11.5 inches. Determine the
volume of the pyramid.
volume:
Answer:
[tex]V = 245\frac{1}{3} in^{2}[/tex]
Step-by-step explanation:
The volume of a pyramid is equal to the area of the base times height divded by three so
[tex]V = \frac{A_{base} h }{3} \\V = \frac{(8^{2})(11.5) }{3} \\V = \frac{736}{3} \\V = 245\frac{1}{3} in^{2}[/tex]

Can anyone please help me with this with an explanation
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+4x−68=34−8x
5x+4x+ −68=34+ −8x
(5x+4x)+(−68)=−8x+34(Combine like terms)
9x+−68=−8x+34
9x−68=−8x+34
Step 2: Add 8x to both sides.
9x −68+ 8x= −8x +34 +8x
17x −68 =34
Step 3: Add 68 to both sides.
17x −68 +68= 34 +68
17x=102
Step 4: Divide both sides by 17.
17x /17= 102/17
X=6 > final answer hope i could help :)
Step-by-step explanation:
Let's step through this line by line, looking for a spot where the friend could have made a mistake.
[tex]5x+4x-68=34-8x\\5x+4x=102-8x\\5x+4x+8x=102\\17x=102\\x=6[/tex]
So, where could the friend have made their mistake? The key here is the transition from step 1 to step 2. What if we had subtracted 68 instead of adding it?
[tex]5x+4x-68=34-8x\\5x+4x=-34-8x\\5x+4x+8x=-34\\17x=-34\\x=-2[/tex]
There it is. The friend's problem was that they had accidentally subtracted 68 to both sides when they should have added it.

(-5,-1); 2y=2x-4 help me ASAP please
(-5, -1) is not a solution to the equation 2y = 2x - 4.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2y = 2x - 4 _____(1)
Ordered pair: (-5, -1)
Now,
(-5, -1) = (x, y)
Substitute in (1)
2y = 2x - 4
2 x (-1) = 2 x (-5) - 4
-2 = -10 - 4
-2 = -14
This is not true.
Thus,
(-5, -1) is not a solution.

everyday finn brushes his teeth 3 times , for 2 min each time , he flosses twice a day , for 5 minutes each time. In a year , how much time does finn spend brushing and flossing his teeth?
Answer:
5,840 minutes
Step-by-step explanation:
Assuming there are 365 days in a year. If finn brushes his teeth 3 times , for 2 min each time then the time spent to brush his teeth in a day
=3 * 2 minutes
= 6 minutes
If he flosses twice a day , for 5 minutes each time, then the time spent in a day to floss
= 2 * 5 minutes
= 10 minutes
Hence total time spent in a day brushing and flossing
= 6 + 10
= 16 minutes
Hence the time spent in a year brushing and flossing
= 16 * 365
= 5,840 minutes

The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4⟩.
Answer:
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)
Step-by-step explanation:
We are given that the vertices of quadrilateral MNPQ are M(-3,-2),N(-1,4),P(2,4) and Q(4,-2).
We have to translate the quadrilateral MNPQ using vector <3,-4>
The translate the coordinates of vertices (x,y) using the vector <a,b> is given by the rule
[tex](x,y)\rightarrow (x+a,y+b)[/tex]
Using the rule
The new coordinates of M
[tex](-3,-2)\rightarrow (-3+3,-4-2)[/tex]
[tex](-3,-2)\rightarrow (0,-6)[/tex]
The new coordinates of N
[tex](-1,4)\rightarrow (2,0)[/tex]
The new coordinates of P
[tex](2,4)\rightarrow (5,0)[/tex]
The new coordinates of Q
[tex](4,-2)\rightarrow (7,-6)[/tex]
Hence, after translation the new vertices of quadrilateral are
M'(0,-6),N'(2,0),P'(5,0) and Q'(7,-6)
Find the equation of the straight line passing through the points (–2, 3) and parallel to y=2x-1
Answer:
[tex]y=2x+7[/tex]
Step-by-step explanation:
All parallel lines have the same slope, so in slope intercept form, our line is going to look like
[tex]y=2x+b[/tex]
To find b, we can plug in the x and y values from the given point (-2, 3) and solve:
[tex]3=2(-2)+b\\3=-4+b\\b=7[/tex]
So our equation becomes
[tex]y=2x+7[/tex]

Answer:
x = 43.5°
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the angles and equate to 360
x + x + 72 + 111 + 90= 360
2x + 273° = 360° ( subtract 273° from both sides )
2x = 87° ( divide both sides by 2 )
x = 43.5°
Answer:
Sum of the angles around a given point is 360°.
[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]

Rectangle FGHJ has diagonals FH and JG that intersect at M. If FJ=−3x+5y, FM=3x+y, GH=11, and GM=13, find the values of x and y. Explain your answer.
Answer:
x=3 y=4
Step-by-step explanation:
-3x + 5y = 11
+ 3x + y = 13
Add the equation (add the 5y and y. Then add the 11 and 13). The threes cancel each other out. It then leaves us with the equation:
6y = 24
Divide both sides by 6 to isolate the variable.
y=4.
Then just substitute the variable into any of the equations above. (I chose the equation on top)
-3x + 5(4) = 11
Then solve
-3x + 20 = 11 (then subtract 20 from both sides)
-3x = -9 (then divide both sides by -3)
x=3
