Question

2. Two angles of a quadrilateral are 68º and 76º.
If the other two angles are in the ratio 5:7,
find the measure of each of them.​

Answer 1

Step-by-step explanation:

sum of given angle is 68+76=144

sum of other two angle is 360-144=216

sum of ratios= 12

angle 1=5/12×216=5×18=90

angle 2=7×18=126

Answer 2

Hi❤️❤️

Two angles are 68° and 76°

Let other two angles be 5x and 7x

∴ 68°+ 76° + 5x + 7x = 360°

12x + 144° = 360°

12x = 360° – 144°

12x = 216°

x = 18°

angles are 5x and 7x i.e. 5×18° and 7×18° i.e. 90° and 126°
