X+x+20+2x=180
4x+20=180
4x=160
x=40
Answer:
∠ B = 85°
Step-by-step explanation:
Complementary angles sum to 90° , then
x - 23 + 2x + 29 = 90 , that is
3x + 6 = 90 ( subtract 6 from both sides )
3x = 84 ( divide both sides by 3 )
x = 28
Then
∠ B = 2x + 29 = 2(28) + 29 = 56 + 29 = 85°
Number one or 2? so i can help you
2.45cm=1 in
times both sides by 63
160.02cm=63 in
about 160cm
