Answer:
-3.5
Step-by-step explanation:
6x + 16 = 2x + 2
4x = -14
x = -3.5
We have to use pythagorean theorem. The equation is

so we plug in the numbers (hypothenuse is always C in the equation)

now we solve:

Subtract
a=6 Square Root
x=6 Answer
Answer:
6.72 feet
Step-by-step explanation:
4.2 x 1.6 = 6.72
You must know that the sum of interior angles is 180°. We also know that AC and BA are congruent which means angles B and C are also congruent. To find x we can assume 25=5x. Which makes x=5, and angle C=25°.
Then we can add all the angles to find y and A. 25+25+(3y+70)=180. Then solve for y and then solve for angle A.
