Question

just do number 3 quick please

Answer 1

Answer:

Step-by-step explanation:

Sin A = $\frac{opposite side}{hypotenuse}=\frac{5}{13}$

Cos A = $\frac{Adjacent side}{hypotenuse}=\frac{12}{13}$

Tan A = $\frac{opposite side}{adjacent side}=\frac{5}{12}$

A = tan⁻¹ (5/12) = 22.61°

Answer 2

Answer:

Step-by-step explanation:

a) Sin A = opposite/hypothenuse

Sin A = 5/13 ≈ 0.3846..

b) Cos A = adjacent/hypothenus

Cos A = 12/13 ≈ 0.9230..

c) Tan A = opposite/adjacent

Tan A = 5/12 ≈ 0.4166..

d) we will use the inverse Sine function

< A = sin^-1(5/13)

< A = sin^-1(0.3846) ≈ 22.62°

P.S. You can use any of the three inverse functions to find the angle: sin^-1 | cos^-1 | tan^-1
