Answer:

100°

Step-by-step explanation:

AB = AC (given)

Therefore, ∆ ABC is an isosceles triangle.

m<B=m< C= 40°

sum of the interior angles of a triangle= 180°

m<A+40°+40°=180°

m<A = 180°-80° = 100°

Answer:

< A is 100

Step-by-step explanation:

<B is 40 <C is also 40

so 40+40= 80 then you have to do 180-80. Which equals 100.

Answer:

6.75 hrs are missing

Step-by-step explanation:

8 = 8

7 1/4 = 7 + 0.25 = 7.25

8 1/2 = 8 + 0.50 = 8.50

Next, add all numbers gotten together:

8 + 7.25 + 8.50 = 23.75

Subtract the number gotten from the total

30.5 - 23.75 = 6.75
