The length of the hypotenuse of a 30 -60 -90 triangle is 11, find the perimeter ?

1 answer:

5 0

Cos(30) = x/11

cos(30) × 11 = 9.53

sin(30) × 11 = 5.5

perimeter = 11+9.53+5.5 = 26.03

Hope this helps

Step-by-step explanation:

you put the values in place of the variable names and calculate.

y² + x + y

(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9
