Respuesta :

90 + 25 + 30 + x = 180. X is 35

Answer:

X is 35.

Step-by-step explanation:

We know that all triangles are equal to 180. and we see a right angle from the bottom left corner, which is 90 so:

180 - 90 = 90

meaning all the other angles must add up to 90. 30 and X make up the top angle so 30 + X + 25 is 30.

90 - ( 30 + 25) = X = 35.

double check.

35 + 30 + 25 + 90 = 180

hope that helps
