Question

One of the exteriour angle of a ABC
measures 150° . if one of the interion opposite
angle is 75° find the other interion opposite
angle, what type of triangle is this​

Answer 1

Answer:

ISOSCELES TRIANGLE

Step-by-step explanation:

The another interior opposite angle is 75 ° and The given triangle is isosceles. Since the two angles are equal So, the opposite sides of equal angles are equal . So, The given triangle is isosceles . Hence the another interior opposite angle is 75 ° and The given triangle is isosceles.

Answer 2

Answer:

Isosceles 75 °

Step-by-step explanation:

Because exterior angle is 150 ° then interior angle will be 30° (suppose A) ( linear pair )

then B will be 180°-(A + C )

= 180 ° - ( 30 ° + 75 ° ) ( angle sum property of a triangle )

= B = 180 ° - 105 = 75 °

Two angles' measures are same
