The total elevation that the scuba driver does is from
![-29 \frac{7}{10}](https://tex.z-dn.net/?f=-29%20%5Cfrac%7B7%7D%7B10%7D%20)
to
![-28 \frac{9}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D%20)
The ascending distance =
![-28 \frac{9}{10}--29 \frac{7}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D--29%20%5Cfrac%7B7%7D%7B10%7D%20)
The ascending distance =
![\frac{4}{5} feet](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20feet)
The time (t) taken during the ascend = 19.125 - 12.75 = 6.375 minutes
The average change in speed is given by the ascending distance divided by time taken during the ascend =
![\frac{4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20)
÷ 6.375 = 0.125 feet/minute

Hello!
3x - 32 = -7x + 28
-32 - 28 = -7x - 3x
-60 = -10x
-6 = -x
6 = x
x = 6
I hope this helps you! Have a lovely day!

Step-by-step explanation:
the triangle is an isosceles triangle hence the base angles are equal
sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)
the top angle =56°
h°= the top angle because alternate angles are equal
hence, h=56°
