The ∠P is equal to 55°
Step-by-step explanation:
We are given three sides of triangle and to calculate the one angle of corresponding to 10 ft side.
Using cosine law:
where,
a = 12 ft
b = 5 ft
c = 10 ft
∠C = ∠P
Substitute into formula
Hence, The ∠P is equal to 55°
c
-by-step explanation:
it would be c
