Question

In a quadrilateral the measure of two angles is equal to the each other of the two angle are in ratio 3 ratio 4 with the sum is 140 degree find the measure of all angles

Answer 1

Answer:

the angles which are in the ratio 3:4

first lets find out their values.

= 3x + 4x = 140

7x = 140

x = 20

angles are 60 and 80 respectively.

now we know that the sum of all the angles of a quadrilateral = 360

therefore the remaining two equal angles will be = 360-140 = 220/2 = 110 each
