Find the value of each variable. I’ll mark you as a brainliest

See below

Step-by-step explanation:

Q11

Triangle is 45° and therefore isosceles

x = 10y = 10√2

Q12

y = 2*7 = 14 as the side opposite to 30° angle is half of the hypotenusex = √14²-7² = 7√3

Q13

x = 32/2 = 16, same reason as abovey = 16√3

Q14

x = y = 6/√2 = 6√2/2 = 3√2

Q15

x = 11√3/√3 = 11y = 2x = 2*11 = 22

Q16

z = 24√2/√2 = 24x = 24√3y = x/2 = 24√3/2 = 12√3
