<u>Answer</u>
5 and -4
<u>Explanation</u>
If the two triangle are congruent then they have the same area.
20 = x² - x
x² - x - 20 = 0
x² - x + (1/2)² = 20 + (1/2)²
(x - 1/2)² = 20.25
x - 1/2 = √20.25
x - 1/2 = 4.5 or x - 1/2 = - 4.5
x = 4 1/2 + 1/2 x = -4 1/2 + 1/2
= 5 = -4
The values of x are 5 and -4.

Answer: C: X=2
Step-by-step explanation:
X=2 BECAUSE if u put 2 instead of the x's then it would be 3(2) +8=4(2)+6

Answer:
x = 8
, y = 8
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and the exact values
sin60° = 
, cos60° = 
sin60° = 
= 
= ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
----------------------------------------------------------
cos60° = 
= 
= ( cross- multiply )
2y = 16 ( divide both sides by 2 )
y = 8
