please jwb bantu please jwb

1.)a. <SRT dan <PQR
b. <SRT = 124 + x = 180
x = 180 - 124
x = 56
<SRT = < PQR
56 = 56

2.) a) a= 100 + x =180
x = 180 - 100
x = 80
a = b
80 = 80

b.) d = c = 55

3.) a.) b = 54
a = 180 - 54 = 126
b.) c = 50
2d = 50/2 = 25
c.) e = 70
2f - 10 = 70
2f = 70+10
2f = 80
f = 80/2
f = 40
