1.) Solve for length b.
The simpler method is to use the Pythagorean theorem. If 
, then this means that 
.
Plug in the values:
--> 
So this means that b is the square root of 72, which is 8.49
2.) Solve for ∠A.
Let's refer to the law of sines. If 
, then this means we can cross multiply. Since A is the value we are solving for, the equation should be written out like this:
--> 
A is 39.52°
3.) Solve for ∠B.
This is the easiest one. The sum of all three angle measures in a triangle add up to 180°. We already know that one of the angles is a right angle and the other 39.52°.
39.52 + 90 = 129.52
180 - 129.52 = 50.48
∠B is 50.48°.
Answer: B and C
Step-by-step explanation:
Let's start off with some definitions.
Supplementary Angles: Two angles that add up to 180°.
Right Angle: One angle equal to 90°. Also identified with a square on the angle.
Complementary Angles: Two angles that add up to 90°.
Straight Angle: A straight line, which equals to 180°.
Right off the bad, we can knock off A and D because there is no proof of those being seen.
The angle <EFH is a right angle because it is equal to 90°. If you pay close attention, the angles <EFG and <GFH both add up to 90°, making them complementary angles.
Therefore, the correct answers are <u>B and C.</u>
I hope this helps! Pls mark brainliest!! :)
Answer:
7,840 
Step-by-step explanation:
You’re answer would be D love!
That would become
(XY)^4/3 .
The exponent is still rational. Sorry.
