Sagot :
Answer:
X = 45°
Y = 72°
Step-by-step explanation:
There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.
Answer:
x = 45° , y = 72°
Step-by-step explanation:
A straight, horizontal line is equal to 180°
x = 180° - 135°
x = 45°
We can find y because we know that all three angles of a triangle equal 180°
So what do we have?
63°, 45°, y
We can make an equation:
180° - (63°+45°) = y
180°- 108° = 72°
y = 72°
