Question

the two angles of a quadrilateral are 70 degree and 80 degree the other two angles are equal in measure find the measure of the two angles

Answer 1

Hey dear!

Here is yr answer.....

two angles of quadrilateral = 70° , 80°

The other two are equal so, x and x are measures


Sum of all angles in a quadrilateral = 360°

70+80+x+x = 360

150+2x = 360

2x = 360-150

2x = 210

x = 210/2

x = 105


Therefore, the two angles measures 105 and 105


Hope it hlpz...

Answer 2

Given two angle are of 70 and 80 degree
So
Let the other angle are x
According to the question
Angle are equal
So
Other angle are of also x
So
70+80+x+x=360( sum of a quadrilateral)
150+2x=360
2x =360-150
2x=210
X=210/2
X=105
So
Other 2 angle are of 105
And other two angle are 70 and 80
So
1st angle is 80
2nd angle is 70
3rd angle is 105
4th angle is also 105




I hope this will helP u
