Question

What are the values of A,B and C? Please show all the work on how you got your answer

Answer 1

Answer:

a=35, b=14, c=5

Step-by-step explanation:

b+6=20, b+6-6=20-6, b=14

4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5

a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35

Answer 2

Answer:

A = 35°

B = 14

C = 5

Step-by-step explanation:

So to start we must assume that noth triangles are the exact same triangle.

to find A we must add up all angles to total 180°

angle A + angle B + angle C = 180°

A + 55° + 90° = 180°

A + 145° = 180°

-145° = -145°

A = 180° - 145°

A = 35°

to find B

B + 6 = 20

-6 = -6

B = 20 - 6

B = 14

to find C

4c - 6 = 14

+ 6 = +6

4c = 20

÷4 = ÷4

C = 20 ÷ 4

C = 5
