What is the value of x?
enter your answer in the box.
x =°c

x = 55

Step-by-step explanation:

well three angles of a triangle = 180 degrees

if you have two add them up and subtract by 180

180 - (75+50) = 125

180 - 125 = 55

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
