To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63

PLEEEEEEEEASE HELP! How the heck do i figure this out!!!?<br> Find m
Fiesta28 [93]
Here is how you find the answer. 
Do remember that the term Bisect means to cut it in half.
So here it goes.
<span>5x = 3x + 10
5x - 3x = 10
2x = 10
x = 5
Then, substitute the values, so 5*5 or 3*5+10
Then, the answer for each smaller angle is 25.
</span>Remember bisect? so 25 x 2 so the final answer is 50.
Hope this is the answer that you are looking for. Thanks for posting your question!

You are asked to draw a triangle with side lengths of 3 inches, 4 inches, and 1 inch. How many triangles like this can you draw?
marishachu [46]
I think you can draw two of them.

As you walk around the triangle in the clockwise direction,
you can run into the sides in the order of

                 3  ==>  4  ==>  1

or in the order of

                 3  ==>  1  ==>  4 .

Those are mirror images of each other.  So they're not congruent,
and I think they're considered different triangles.
