Answer:

Step-by-step explanation:

We can use ratios to solve

15 ft 18ft

---------- = -----------

5ft x

Using cross products

15x = 5*18

15x = 90

Divide by 15

15x/15 = 90/15

x =6

3. Find the angle complementary to the angle 80°25′. A. 180° B. 9°35′ C. 90° D. 99°35′

svetlana [45]

"Complementary" angles sum to 90°.

Since we are using minutes as well...

80°+d°+25'+m'=90° subtract 80° from both sides

d°+25'+m'=10° subtract 25' from both sides

d°+m'=9°+60'-25'

d°+m'=9°+35'

9°35'

$\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}$

$\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}$

$\text {Difference = }5.97 \times 10^{24} - 4.87 \times 10^{24}$

$\text {Difference = }(5.97 - 4.87) \times 10^{24}$

$\text {Difference = }1.1 \times 10^{24} \text { kg}$

--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24}
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg
