Answer 1

∠C = 16.26°

Explanation:

Since the adjacent side and the hypotenuse are given, let's take the cosine value of ∠C.

============================================================

Given :

⇒ Adjacent side (CB) = 24 cm

⇒ Hypotenuse (CA) = 25 cm

==========================================================

Taking the cos value :

⇒ cos ∠C = CB/CA

⇒ cos ∠C = 24/25

⇒ ∠C = cos⁻¹ (0.96)

⇒ ∠C = 16.26°

Answer 2

`\angle C = 16.26^(\circ)`

Explanation:

`~~~~~~\cos \theta = \frac{\text{Base}}{\text{Hypotenuse}}\\\\\\\implies \cos \angle C = (BC)/(AC)\\\\\\\implies \angle C = \cos^(-1) \left((BC)/(AC)\right)\\\\\\\implies \angle C=\cos^(-1) \left((24)/(25)\right)\\\\\\\implies \angle C = 16.26^(\circ)`
