A. AB
B. BC
C. CA
Answer:
A. AB
Step-by-step explanation:
The hypotenuse is the opposite side of where the right angle is. Therefore, AB would be the hypotenuse.

True or false: The cross section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.
Options:
True
False
True, as there is no guarantee that it will be symmetrical.
What is Geometry?Geometry is defined as the study of two-dimensional or three-dimensional figures like quadrilaterals, Triangles, circles their sides, and angles.
Symmetry is defined as if the object is cut by its center line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.
Depending on the cut's direction (horizontal or vertical), a 3D object's cross-section may appear differently.
Therefore, the given statement is true that the cross-section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

Solve for x
Answer:
the answer is 10
Step-by-step explanation:
92+78=170
180-170=10
theres 180 beacuse every straight line has the angle of 180
Answer:
x = 10
Step-by-step explanation:
These 3 angles are supplementary so they all equal 180:
92 + x + 78 = 180
x + 170 = 180
x = 10

51. Find the length of the unknown side x of this triangle, evaluate your answer to two decimal places.
Answer:
See work, below.
Step-by-step explanation:
The radius of this circle is 10 and so the diameter is 20. The measure of the angle opposite side x is found as follows:

cos theta = ------------------- = 18/20. Find theta:
hypotenuse
theta = arccos 18/20 = 0.451 radian.
Now use the sine function to find x:
x x
sin 0.451 radian = ------------------- = ------------- = 0.651
hypotenuse 20
which results in x = 20(0.651) = 13.02
x = 13.02 units
I should have used the Pythagorean Theorem up front.
18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72
Calculate the area of each shape below. Figures are not drawn to scale.
Answer:
sorry its impossible to take out the ans of this
Answer:
A = 168 m²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 8 + 16 = 24 and h = 14 , then
A = [tex]\frac{1}{2}[/tex] × 24 × 14 = 12 × 14 = 168 m²
Which one of these four sets of side lengths will form a right triangle?
Please help me.
Don’t give me fake answer or I will report you.
=======================================================
Explanation:
If a regular polygon has n sides, then each interior angle has the measure of
i = 180(n-2)/n
In this case, we have n = 6 sides, so,
i = 180(n-2)/n
i = 180(6-2)/6
i = 120
Each interior angle of a regular hexagon is 120 degrees.
This means the bottom-right angle of the triangle is 120 degrees. The upper-right angle of that triangle is shown to be x degrees. The remaining angle is also x due to the triangle being isosceles (recall that regular hexagons have all sides the same length). Isosceles triangles have congruent base angles, which are opposite the congruent sides.
Use the fact that for any triangle, the three angles always add to 180, and we get...
x+120+x = 180
2x+120 = 180
2x = 180-120
2x = 60
x = 60/2
x = 30

Solve for x
Answer:
x = 156
Step-by-step explanation:
These angles are supplementary so they add up to 180:
x - 5 + 29 = 180
x + 24 = 180
x = 156
Answer:
x = 156
Step-by-step explanation:
The line equals 180 degrees, and the angle 29 degrees is already given.
180-29 = 151
This means that the other angle must be 151 degrees.
(x - 5)°
If we replace 156 with x, we will get 151 degrees, so that means x = 156.
(156 - 5)° = 151°
Teresa is maintaining a campfire. she has kept the fire steadily burning 4 hours with 6 logs. She wants to know how many logs she need to keep the fire burning for 18 hours. Select the equations tessa can use, and determine the number of logs she needs to maintain the fire for 18 hours. Select all that apply.
A. X/6=4/18
B. X/6=18/4
C. X/18=6/4
D. X/4=18/6
E. 4/6=18/X
Step-by-step explanation:
Let x be the number of logs=18 hours
6 logs=4 hours
X*4=18*6
4x=108
x=27 logs
so therefore 27 logs are needed to keep the fire burning for 18 hours

Find the x-intercept of the function y=−0.2x+0.55
Answer:
2.75
Step-by-step explanation:
y=0
−0.2x+0.55=0
0.2x=0.55
x=2.75
Answer:
x=-2.75
Step-by-step explanation:
Plug y=0 into the equation and solve for x:
y=-0.2x+0.55
0=-0.2x+0.55
-0.55=0.2x
-2.75=x
Therefore, x=-2.75

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Part A
Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B
Use the Distributive Property to solve the equation.
Enter your answer in the box.
$
Answer:
`Part A:
D. 3/4(18 + s) = 31.50
Part B:
$36
Step-by-step explanation:
I think 34 is 3/4, is that right?
here, s is the cost of the skirt
Part A: The answer would be:
3/4(18) + 3/4(s) = 31.5 =
3/4(18 + s) = 31.5
Part B: 3/4(18) + 3/4(s) = 31.5
4.5 + 3/4s = 31.5
Subtract 4.5 from both sides:
3/4s = 27, 27 is the cost of the skirt now, but we need the original price.
multiply both sides by 4/3:
s = 36
