Question

Find the value of n so that PQRS is an isosceles is an isosceles trapezoid

Answer 1

Answer: it’s 11.5

Step-by-step explanation: I got it right

Answer 2

n=7.5°

Explanation:

As the two lines are parallel do the equation is

(10n+19)+(12n-4)=180

10n+19+12n-4=180

22n+15=180

22n=180-15

22n=165

n=165/22

n=15/2

n=7.5

n=7.5°
