Answer: cos30
Step-by-step explanation:
The area is 100 because 15*B(9)=100
Answer:
-5x + 8y = -21
3x - 4y = 15
8y = 5x - 21
y = 5/8x - 21/8
3x - 4y = 15
-4y = -3x + 15
y = 3/4x - 15/4
5/8x - 21/8 = 3/4x - 15/4
-1/8x = -9/8x
x = 9
3x - 4y = 15
3(9) - 4y = 15
27 - 4y = 15
-4y = -12
y = 3
(9, 3)
<u>Given</u>:
Given that the bases of the trapezoid are 21 and 27.
The midsegment of the trapezoid is 5x - 1.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trapezoid midsegment theorem.
Applying the theorem, we have;

where b₁ and b₂ are the bases of the trapezoid.
Substituting Midsegment = 5x - 1, b₁ = 21 and b₂ = 27, we get;

Multiplying both sides of the equation by 2, we have;

Simplifying, we have;

Adding both sides of the equation by 2, we get;

Dividing both sides of the equation by 10, we have;

Thus, the value of x is 5.
Answer:
-9
Step-by-step explanation:
(x + 89)° + (x + 109)° = 180°
(interior angles on the same side of transversal)
(2x + 198)° = 180°
2x + 198 = 180
2x = 180 - 198
2x = - 18
x = - 18/2
x = - 9
