Answer 2

Answer:

a) 50⁰ is missing angle

b) 80⁰ is missing angle

c) 30⁰ is Missing angle

Step-by-step explanation:

in a ) one angle is of 40⁰ and another of 90⁰ so by angle sum property 40+90+x=180 x = 180-130 = 50 so missing angle is 50⁰

In b) one angle is of 60⁰ and another of 40 so by angle sum property 60+40+x=180, x= 180-100= 80 so missing angle is 80

in c) one angle is 125 another is of 25 so by angle sum property 125 + 25 + x = 180, x = 180-150=30 so missing angle is 30⁰
