Question

please find r, s, and t​

Answer 1

Answer:

r=100° ,s=40° , t=60°

Step-by-step explanation:

l//m

=> s+140=180

s=180-140

s=40°

m//n

=> 120+t=180

t=180-120

t=60°

->t=r2

r2=60°

->s=r1

r1=40°

=>r=r1+r2

r=60+40

r=100°

OR

140+r+120=360°(complete angle)

r=360-140-120

r=100

Answer 2

Answer:

r = 100 degree

Step-by-step explanation:

As , in the case of the r angle we have , a 360 degree angle

so , 140 + 120 + r = 360

260 + r = 360

r = 360 - 260 = 100 degrees
