Question

Can someone provide some assistance.​

Answer 1

m<E=120°

m<T=60°

Explanation:

10m+4m+12=180

14m=168

m=12

m<E=10m=10(12)=120

m<T=4m+12=4(12)+12=48+12=60

Answer 2

Solution given:

10m+4m+12=180°[sum of opposite angle of cyclic quadrilateral is supplementary]

14m=180-12

m=168/14=12

m<E=10×12=120°

m<T=4×12+12=60°
