Answer:
t = 110°
Step-by-step explanation:
Triangle BCD is isosceles, so its base angles are congruent. This means m<CBD = m<CDB. Since m<CBD is 35, m<CDB is also 35.
The sum of angles in a triangle is 180, so the following equation can be written:
180 = m<CBD + m<CDB + m<BCD
We can substitute m<CBD and m<CDB with 35 and m<BCD with t and solve:
[tex]180 = 35 + 35+ t\\180=70+t\\t=110[/tex]
So t = 110°

What is right angle triangle property?In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.
[tex]\tan\theta=\dfrac{b}{a}[/tex]
Here, (a) is the base side, (b) is the opposite side.
Let suppose y is the length of opposite side in a unit circle and x is the length of base side. Thus, the value of tan theta is:

Which polynomial function gets larger and larger in the negative direction as x gets
larger and larger in the negative direction?
A./(x) = 5x² - 2x+1
B./(x) = 6x³+4x² - 15x+32
G./(x) = 7x"=2x+3x²+8x-10
D. /(x) = 8x6 +- 1
Answer:
f(x) = 8x^6 + 1
Step-by-step explanation:
We want to examine which polynomial function grows larger and larger as the negative variable rises. We'll see that option d is correct: f(x) = 8x6 + 1
There are two things to keep in mind here.
The polynomial grows quicker as the exponent increases.
When a negative integer is evaluated with an even exponent, the result is always positive.
Then all the polynomials with an even leading exponent become larger and larger as x grows in the negative direction, especially the one with the biggest leading exponent, which is:
is 300 greater than 8/9?

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
Yes, 300 is greater than [tex]\bold{\dfrac{8}{9}}[/tex].
Remember, proper fractions (fractions with a numerator less than the denominator) are less than 1.
When comparing an integer (like 300) with a fraction (like 8/9), first you need to work out whether or not the fraction is a proper fraction.
Then, you also need to pay attention to the signs, because they may seem trivial, but they are in fact highly significant.
Therefore,
300>8/9 (300 is definitely greater than a number less than 1, right?)
(and the ">" sign means "greater than"

Answer:
m∠R = 72°; m∠U = 65°
Step-by-step explanation:
We know that in any quadrilateral, the total sum of the angles will always add up to 360°.
For number 26, we can use this equation to find x and m∠R:[tex]90+98+12x+4+10x-8=360\\(90+98+4-8)+(12x+10x)=360\\184+22x=360\\22x=176\\x=8[/tex]
m∠R = 10 (8) - 8 = 80 - 8 = 72°
For number 28, we can use this equation to find x and m∠U
[tex]96+88+11x+1+7x-5=360\\(96+88+1-5)+(11x+7x)=360\\180+18x=360\\18x=180\\x=10[/tex]
m∠U = 7 (10) - 5 = 70 - 5 = 65°

2. The bases of the trapezisid (x-14) cm and (x+2) cm ats medien is 30 cm long, how long is the shorter base
Answer:
22cm
Step-by-step explanation:
Formula:
MEDIAN = 1/2(B1+B2)
Solution:
30= 1/2[(x-14)+(x+2)]
x = 36 cm
B1= 36-14 = 22 cm (shorter base)
B2= 36+2 = 38 cm (longer base)
The Shorter Base is 22cm.
Can someone please help me with this
Answer:
First step, find the missing angle (you will need this later on)
We know that the sum of all angles in a triangle equals to 180°, so
180° - 65° - 40° = 75° *that's your angle (next to the point L)
Now, identify each side (as shown in my drawing attached to this message)
The law of sines tells us that
(for example) the side opposite to L (highlighted in pink in the drawing) divided by the sine of the angle at the point L (in our case, 75°) creates a ratio that remains the same for the other sides.
So,
pink side (opposite to L)/ sin 75 (angle at L) = yellow side (opposite to J)/ sin 65 (angle at J) = blue side (opposite to K)/ sin 40 (angle at K)
*Careful, since we were not given the length of one side, you cannot find actual values for each side. Although, you can use the law of sines to logically find out which length is the longest and which one is the shortest.
*Notice that the sine of the angle relates to the length of the coloured sides
Calculate the following: sin 75, sin 40, sin 65.
Once you do that, you will realize that sin 40 = to the smallest value and that sin 75 gives you the largest value.
Thus, sin 40 < sin 65< sin 75
Which corresponds to (from smallest to largest):
blue side, yellow side, pink side
*Now, write your answer in a mathematical format (using J,L,K points)
blue = JL (explanation: it connects the two points, LJ is also a valid answer)
yellow = LK
pink= JK
ANSWER: JL, LK, JK
Step-by-step explanation:
Use the Law of Sines *because you don't have a right angle triangle.
