1.	Two angle of a quadrilateral are of measure 80° each .the other two angle are also equal.what is the measure of either of these two angles ?
Answer» Answer: Step-by-step explanation: The measures of two angles of a triangle are 72° and 58°. Let the third ANGLE be X. Now, the sum of the measures of all the angles of a triangle is 180O. ∴ x + 72o + 58o = 180o ⇒ x + 130o = 180o ⇒ x = 180o - 130o ⇒ x = 50o The measure of the third angle of the triangle is 50o.

Answer:

Step-by-step explanation:

The measures of two angles of a triangle are 72° and 58°.

Let the third ANGLE be X.

Now, the sum of the measures of all the angles of a triangle is 180O.

∴ x + 72o + 58o = 180o

⇒ x + 130o = 180o

⇒ x = 180o - 130o

⇒ x = 50o

The measure of the third angle of the triangle is 50o.
