Answer:

t=75 3x=75 and y=30

Step-by-step explanation:

t and 3x are equivalent because the sides are the same lengths. knowing that you can subtract 105 from 180 getting 75 for t, knowing that t and 3x are equivalent you also get the answer for 3x witch is 75. the sum of all the angles is 180 and adding 3x and t you get 150, subtracting 150 from 180 you get 30 the answer to degree y.

A straight line is 180°.

t + 105° = 180°

t = 180° - 105°

t = 75°


The triangle is in the picture is an isosceles.

The bottom triangle of an isosceles is the same.

t = 3x

75° = 3x

x = 25°


The sum of all the angles in a triangle is 180°.

y + 3x + t = 180°

y + 3(25°) + 75° = 180 °

y + 75° + 75° = 180°

y = 180° - 150°

y = 30°
