Answer:

50*0.1=5

Step-by-step explanation:

So 90% off of 50 looks like 50-90%. 50-90%=50*1-0.9*50 since 90% is 9/10 and we are doing 90 percent off of 50. 50*1-0.9*50=50*0.1=5. So $5.

Group b.. pls help me

Artemon [7]

Answer:

Step-by-step explanation:

m∠ABC + m∠BAC + m∠ACB = 180°

a + 2a + 6a = 180°

9a = 180°

a = 20°

m∠ABC = 20°

m∠BAC = 2 × 20° = 40°

m∠ACB = 6 × 20° = 120°
