-1 for apex i just answered this question and got it right
Answer:
800.8
Step-by-step explanation:
Let, the height be h.
Then, sin72 = h/842
h = sin72 * 842
= 800.7895 = 800.8
[please inform if I'm wrong]
Answer:
A is the answer.
Step-by-step explanation:
All of the points are together and the line is going down. PLEASE MARK BRAINLIEST!!!!!!!!!!
That's a question about the Pythagorean Theorem.
We use the Pythagorean Theorem to find the value of one side in a right triangle.
This theorem says that:

- <em>a</em> is the hypotenuse (It's the opposite side the right angle).
- <em>b</em> and <em>c </em>are cathetus (They're the adjacent sides the right angle).
Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of <em>x </em>(the hypotenuse). Let's change this information in that formula.

Therefore, the value of <em>x </em>is
.
I hope I've helped. :D

The values based on the calculus computed will be 10✓5, 10✓1, and 20.
<h3>How to calculate the value?</h3>
dy/dt = 5 units.
Differentiate with respect to t.
dx/dt = 1/2✓x dx/dt
dyldt = 5.
dx/dt = 2✓x × 5 = 10✓x
a. When x = 1/5
dx/dt = 10 × ✓1/5 = 10✓5
b. x = 1
Differentiate it
dx/dt = 10✓1
c. x = 4
dx/dt = 10✓4 = 20
