Question

find the sum of x + y + z in the following figures​

Answer 1

Answer:

x+y+z = 125°+145°+90° = 360°

Answer 2

we know that sum of all angles in triangle is 180°.

given x = x, y = y, z = 90°.

then x+y+z = 180°.

x+y+90° = 180°.

x+y = 180°-90°.

x+y = 90°

then y = 180° - 35° = 145°.

then x= 180- (90+35).

then x = 55°.

then x = 180°-55°= 125°.

then x+y+z= 145+125+90 = 360°.
