answer:

・x = 50

・y = 61

Explanation:

・first things you should know —

y + 8 + 2x + 11 = 180 ( supplementary angles equal to 180° )

・five sides add up to 540° ( pentagon! )

・therefore:

108 + 125 + 98 + 98 + 2x + 11 = 540

440 + 2x = 540

2x = 100

x = 50

use what you know and plug in ;

y + 8 + 2x + 11 = 180

y + 8 + 2(50) + 11 = 180

y + 119 = 180

・y = 61

you can always plug in or substitute to check your answers.ᐟ
