Question

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

Answer 1

Answer:

$\sf a=\boxed{13}\:cm$

Step-by-step explanation:

Trigonometric ratios

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

• $\theta$ is the angle
• O is the side opposite the angle
• A is the side adjacent the angle
• H is the hypotenuse

Given:

• $\theta$ = 31°
• O = a
• H = 25 m

$\implies \sf \sin(31^{\circ})=\dfrac{a}{25}$

$\implies \sf a=25\sin(31^{\circ})$

$\implies \sf a=12.87595187...\:cm$

Therefore, a = 13 cm (to the nearest whole number)
