Question

What is the length of one leg of the triangle?

O 9 cm
O 92 cm
O 18 cm
1872 cm

Answer 1

9
`√(2)`

Explanation:

To find the answer of this equation, you would use the law of sine

so... (18)/sin(90)= (x)/sin(45)

to find for the length of one side simply isolate for x.

Because sin(90) equals 1, you just have to multiply 18 by sin(45) which equals
`√(2)`/2

so x= 9
`√(2)`
