Question

What is the length c of the right triangle, rounded to the nearest
tenth?

Answer 1

6.1

Explanation:

we will name the length in front of the angle , y :

tan(71°)≅2.904= y ÷2

⇒ y= 5.8

and we know that

c =
`\sqrt{2^(2) + y^(2) }`

then

c = 6.14

and if we round it to the nearest tenth :

c = 6.1
