Answer:
ive seen this before its not to teach what you think stay away from it
Answer: 
Step-by-step explanation:
To solve the exercise you must solve for b from the formula for the hypotenuse, as you can see below:
- Square both sides of the equation as following:

- Now you must subtract a² from each side of the equation, then you obtain:


- Apply square root to both sides:

Then:

Answer:
c is 110 degrees
b is 70 degrees
a is 20 degrees
Step-by-step explanation:
for c, 180-70=110
for b, 180- angle c=180-110=70
for a, 180-90-angle b=180-90-70=20
