Answer:
1.4
Step-by-step explanation:
10 decreased by 1.4 is 18.6
Answer:
red 420 times
Step-by-step explanation:
The results show red (18) out of ( 18+10+7+19+6)
18 / 60
18/60 * 1400 = 420 times
Answer:
6 cm for both sides
Step-by-step explanation:
Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
