What is the measure of Angle B A C?

Triangle A B C. Angle B is 50 degrees, angle C is 50 degrees, and angle A is blank.

50 degrees
80 degrees
100 degrees
130 degrees

80 degrees

Step-by-step explanation:

a a triangle measures 180 degrees. can you add 50 + 50 to get 100. 180 - 100 to get 80

80 degrees

Step-by-step explanation:

rule : angles in a triangle add up to 180 degrees

so 50+50=100 and 180-100=80

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
