I’ll give 20 points.

m∠AYB = 85°

m∠C = 50°

Step-by-step explanation:

By is the angle bisector of ∠ABC,

Therefore, m∠1 = m∠2 = 30°

m∠3 = 35°

m∠AYB + m∠YAB + m∠ABY = 180°

m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]

             = 180° - [(30° + 30°) + 35°]

             = 180° - 95°

             = 85°

m∠A + m∠B + m∠C = 180°

2(30°) + 2(35)° + m∠C = 180°

60° + 70° + m∠C = 180°

m∠C = 180° - 130°

m∠C= 50°

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
