Question

How do i solve this????

Answer 1

...A: we know the opposite side (CB) and the adjacent side (CA)

--->tanA=CB/CA=a/b=3/4 =0.75

Arctan(0.75)=36.86989..=36.9°

Â=36.9°

B: we know the opposite side (CA) and the adjacent side (CB)

--->tanB=CA/CB=b/a=4/3

Arctan(4/3)=53.13012....=53.1°

^B=53.1°

Explanation:

Answer 2

C=5

a^2+b^2=c^2

4^2+3^2=16+9=25

sqrt of 25 = 5

c=5

In a 90 triangle, the other 2 degrees will always be 45 degrees

angles a and b are both 45
