Question

what is the answer of these question plz tell anyone

Answer 1

Answer:

angle BAC + angle ABC = angle ACD [the resultant exterior angle formed is equal to the sum of the measures of the two opposite interior angles of the triangle]

angle BAC + 25° = 70°

angle BAC = 70° - 25°

angle BAC = 45°

In triangle ABC

angle A + angle B + angle C = 180°[sum of all angle of triangle is 180°]

45° + 25° + angle C = 180°

60° + angle C = 180°

angle C = 180° - 60°

angle C = 120°

Answer 2

Step-by-step explanation:

We know that, The sum of two opposite interior angles of a triangle is equal the measure exterior angle.

So given: Exterior angle is 70° and one of the interior opposite angle is 25°

Suppose the other interior opposite angle is x°

Then,

x° + 25° = 70°

x° = 70° - 25°

x° = 45°

so the other interior opposite angle is 45°
