What is the measure of a, in degrees?

B

Step-by-step explanation:

Since AB = AC = 8 then the triangle is isosceles and

∠C = ∠B = 30° ( base angles of an isosceles triangle )

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the base angles from 180, hence

∠A = 180° - (30 + 30)° = 180° - 60° = 120° → B

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
