Question

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

Answer 1

a=13m

Explanation:

that's it in the picture

Answer 2

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

Explanation:

Trigonometric ratios

`\sf \sin(\theta)=(O)/(H)\quad\cos(\theta)=(A)/(H)\quad\tan(\theta)=(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))=(a)/(25)`

`\implies \sf a=25\sin(31^(\circ))`

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

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