Answer:
a = 18.6 ft ; b = 16.7 ft ; ∠B = 42° ; ∠C = 90°
Explanation:
Trigonometry ratios:
c = 25 ft
∠C = 90°
∠A = 48°
Using angle sum property of triangle, we can find ∠B.
∠B = 180 - 48 - 90
= 180 - 138
= 42°
We can find a and b using trigonometry ratio Sin and Cos.

0.7431*25 = a

To find the value of b, use Cosine ratio,

0.6691 * 25 = b
