.7 and 7 are related because:

-If you move the decimal point left or right depending, they are the same number.

-They both stand for a value.

In triangle WXY, the measure of angle W is 3 degrees less then the measure of angle X and the measure of angle Y is 6 degrees le

Anna [14]

Answer:

X = 63°

W = 60°

Y = 57°

Step-by-step explanation:

W = X - 3

Y = X - 6

X + W + Y = 180 substitute

X + (X - 3) + ( X - 6) = 3 X - 9 = 180

3X = 189

X = 63

W = 60

Y = 57

The distance from the sun is option 2 5.59 astronomical units.

Step-by-step explanation:

Step 1; To solve the question we need two variables. P which represents the number of years a planet takes to complete a revolution around the Sun. This is given as 13.2 years in the question so P = 13.2 years. The other variable is the distance between the planet and the sun in astronomical units. We need to determine the value of this using the given equation.

Step 2; So we have to calculate the value of 'a' in Kepler's equation. But the exponential power $\frac{3}{2}$ is on the variable we need to find so we multiply both the sides by an exponential power of $\frac{2}{3}$ to be able to calculate 'a'.

P = $a^{\frac{3}{2} }$ , $P^{\frac{2}{3} }$ = $a^{\frac{3}{2}*\frac{2}{3} }$ , $P^{\frac{2}{3} }$ = a, $13.2^{\frac{2}{3} }$ = a = 5.58533 astronomical units.
