Answer:

m∠A = 144°, m∠B = 36°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees.

Substitute 4(m∠B) for m∠A.

4(m∠B) + m∠B = 180

5(m∠B) = 180

Substitute 36 for m∠B.

4(36) = m∠A

Answer:

2.0 x $10^{1}$

Step-by-step explanation:

1. length = 3.2 x $10^{5}$ m

width = 1.6 x $10^{4}$ m

Area of a rectangle = length x width

= (3.2 x $10^{5}$ ) x (1.6 x $10^{4}$ )

= 5.12 x $10^{9}$ $m^{2}$

2. length = 1.28 x $10^{7}$ m

width = 8 x $10^{3}$ m

Area of a rectangle = length x width

= (1.28 x $10^{7}$ ) x (8 x $10^{3}$ )

= 1.024 x $10^{11}$ $m^{2}$

$\frac{Area of rectangle 2}{Area of rectangle 1}$ = $\frac{1.024*10^{11} }{5.12*10^{9} }$

= 20

= 2.0 x $10^{1}$

Thus,

The area of rectangle 2 is 2.0 x $10^{1}$ times greater than the area of rectangle 1.
