Question

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 1

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 2

Answer:

100° is the required angle.

Step-by-step explanation:

let the measure of required angle be x°.

we know that, sum of angles of a quad. is equal to 360°.

so,ATQ

80°+80°+x°+x°=360°

160°+2x°= 360°

2x°=360° - 160°

2x°=200°

x°=200°/2

=100°

so, required angle is 100° each.
