Answer 2

Answer:

70 degree

Step-by-step explanation:

angle S + angle T+ angle U + angle v =360degree

angle U + angle v+ 80 + 40=360 degree

angle U + angle v=360-140= 220 degree

half of angle U + half of angle v=220/2=110degree

in the triangle formed by the bisector of angle u and angle v÷

angle UOV + half of angle U + half of angle V= 180 degree

angle UOV + 110 = 180 degree

angle UOV=180-110

angle UOV= 70 degree
