Answer:
Step-by-step explanation:
let l be length of string.
Then 70/l=sin 40
l=70/sin 40 ≈108.9 ft
Answer:
It is 3*10^6 times bigger
Step-by-step explanation:
<u>9*10^-4</u>
3*10^-10
=9/3*10^(-4-(-10))
=3*10^6

Since one box contains 5 cups then, two boxes equals <u>10 servings</u>.
Answer: 18°
Step-by-step explanation:
Complementary angles are any two angles whose sum is 90 degrees. Hence, if angles x and y are complimentary, we can say
x + y = 90°
Therefore, the complimentary angle of 72° is obtained by subtracting 72° from 90°
i.e 90° - 72° = 18°
Thus, the complimentary angle of 72° is 18°
Answer:
20
Step-by-step explanation:
The two given and marked angles add up to 90.
A = x
B = 3x + 10
A + B = 90 Substitute for A and B. A and B are just letters I gave things.
x + 3x + 10 = 90 Combine the left
4x + 10 = 90 Subtract 10 from both sides.
4x +10-10 = 90-10 Combine
4x = 80 Divide by 4
4x/4=80/4
x = 20
