Question

Pls help me, show work step by step

Answer 1

c ≈ 9.43

C = 32 degrees

Explanation:

we learn that:

AB^2 = AC^2 + CB^2 so in this case:

c^2 = 5^2 + 8^2

c^2 = 25 + 64

c^2 = 89

c^2 =
`√(89\\)`^2

c = 9.43

Because ACB is perpendicular angle so it would be 90 degrees

CAB is 58 degrees angle

We know that 3 angle in a triangle must = 180 degrees

So, CBA = 180 - 90 - 58

= 32 degrees

Hope this helped :3
