Answer:

58°

Step-by-step explanation:

<MQR = <XQL (vertically opposite angles)

28 + 5b = 70 - 2b

28 - 70 = -2b - 5b

-42 = -7b

-42/-7 = b

6 = b

<MQR = 28 + 5b

= 28 + 5(6)

= 28 + 30

= 58°

Answer:

(A)

Step-by-step explanation:

<XQL and <MQR are vertical angles, which means that their measures are equal to each other.

I used the two equations to solve for b.

[see first picture]

When B got solved, I replaced b in MQR's equation with 6 (B = 6), and I got 58, which is option A.

Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet d

Dafna11 [192]

It's not perfectly clear, but you seem to be saying that each week, the
pond becomes 3% deeper than it was THE PREVIOUS WEEK.

If I'm reading that correctly, then the pond is 10-ft deep when the rainy
season begins, and after 'x' weeks later, the depth is

   D = 10 (1.03)^x feet.

After 8 weeks, the depth is D = 10 (1.03)⁸ = 12.67 feet .

       rounded to the nearest foot, D = 13 ft.
