Question

How do I find the x and the y

Answer 1

Answer:

x = 22

y = 35

Step-by-step explanation:

Because its an isosceles triangle, you know the base angles are equal so:

$3x - 11 = 2x + 11$

Solving:

subtract 2x from both sides

$x-11=11$

add 11 to both sides

$x = 22$

Next, find the angle measures of the two base angles:

$3*22-11\\66-11\\55$

To find y, you know that the interior angles of the whole triangle add up to 180, so you have

$55 + 55 + 2y = 180$

solving,

$110 + 2y = 180$

subtract 110 from both sides

$2y = 70$

divide both sides by 2

$y = 35$

Answer 2

Answer:

x =22°

y =35°

Step-by-step explanation:

3x-11 = 2x+11

then x =22°

and 2y = 180-(55+55)

2y = 70

y = 45°
