Question

one of the angles of a triangle is 100° and the other two angle are equal. find the measure of each of the equal angles​

Answer 1

Answer:

40°

Step-by-step explanation:

Because the sum of all angles in the triangle is 180°

Answer 2

Answer:

To Find : In the figure given alongside, find the measure of ∠ACD.

In the given figure, side BC of ΔABC is produced to D.

Consider the ΔABC,

We know that the exterior angle of a triangle is equal to the sum of its interior opposite angles.

∴ ∠ACD = ∠ABC + ∠BAC

∠ACD = 45° + 75°

∠ACD = 120°

Hence, the measures of ∠ACD is 120°.
