Question

find Angle AAngle B and angle C




​

Answer 1

Answer:

The Answer Is Given Below

Step-by-step explanation:

$a + b + c = 180 \: angle \: sum \: property \\ \\ 7x - 20 + 2x + 15 + 4x - 10 = 180 \\ 13x + - 15 = 180 \\ 13x = 180 + 15 \\ 13x = 195 \\ x = \frac{195}{13} \\ x = 15$

next

$7x - 20 \\ 7 \times 15 - 20 \\ 85 = a$

angle A =85

$2x + 15 \\ 2 \times 15 + 15 \\ 30 + 15 \\ 45 = b$

angle B = 45

$4x - 10 \\ 4 \times 15 - 10 \\ 50 = c$

angle c = 50
