First we need to calculate the 2 angles that make up Angle B at the top of the triangle.
Using that angle we can find the length of CD.

See the attached picture:

D. 26.

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find the length of CD.

We will use altitude on hypotenuse theorem to solve our given problem.

$\frac{CD}{\text{Altitude}}=\frac{\text{Altitude}}{AC}$

Upon substituting our given values, we will get:

$\frac{CD}{37}=\frac{37}{53}$

$\frac{CD}{37}\times 37=\frac{37}{53}\times 37$

$CD=\frac{37\times 37}{53}$

$CD=\frac{1369}{53}$

$CD=25.830188679\approx 26$

Therefore, the length of CD is 26 units and option D is the correct choice.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
