if the two interior opposite angles of a triangle are 50 and 70 degree

1.	if the two interior opposite angles of a triangle are 50 and 70 degree, find the measure of the unknown exterior angle x
Answer» Answer: The value of X is 120°. Explanation: The TWO interior opposite angles are of 50° and 70° positively. According to the exterior ANGLE PROPERTY of a TRIANGLE, the sum of these two angles will be equal to angle x. So, 50° + 70° = x Hence, the value of x is 120°. The exterior angle property of a triangle : the exterior angle of a triangle is equal to the sum of the two interior opposite angles of the triangle. Refer to the attachment. :)

Answer»

Answer:

The value of X is 120°.

Explanation:

The TWO interior opposite angles are of 50° and 70° positively. According to the exterior ANGLE PROPERTY of a TRIANGLE, the sum of these two angles will be equal to angle x.

So, 50° + 70° = x

Hence, the value of x is 120°.

The exterior angle property of a triangle : the exterior angle of a triangle is equal to the sum of the two interior opposite angles of the triangle.
