If $\sqrt{5+n}=7$, then what is the value of $n$?
alina1380 [7]

Answer:

44

Step-by-step explanation:

We can solve the equation by simplifying it.

$\sqrt{5+n}=7$, let's square both sides.

5+n = 49. Now lets subtract 5 from both sides.

n = 44.

Hope this helped!

Find the measure of the indicated angle to the nearest degree.
eimsori [14]

1. use sin

inverse of sin(44/57) = 50.5 ---> 51°

2. use tan

inverse of tan(6/8) = 36.8 ---> 37°

3. use cos

inverse of cos(20/31) = 49.8 ---> 50°

4. use sin

inverse of sin(37/58) = 39.6 ---> 40°

This is a problem pertaining projectile motion wherein the parameter we're finding is the angle of inclination denoted as theta. The formula to be used is the range:

Range = v^2*sin(2*theta)*(1/g)
100 = (60^2) * sin(2*theta) * (1/32.2)
theta=31.7°

I hope I was able to help you. Have a good day!

Answer:

The SAS(Side-Angle-Side) triangle congruency theorem can be used to prove Triangle MNL is congruent to ONP.

Step-by-step explanation:

We would use the side-angle-side theorem because the two triangles both have two equal sides and one angle. For instance, side MN has two lines and so does side ON has two lines. Same goes with sides NL and NP.

Hope this helps!!! PLZ MARK BRAINLIEST!!!

5 - 8x < 2x + 3

5 - 8x < 2x + 3
<u>-3               - 3 </u> Step 1.
2 - 8x < 2x
<u>   +8x    +8x    </u> Step 2. Missing step
2        < 10x
<u>÷10        ÷10</u>   Step 3.
<u>2/10   < x</u>
<u>1/5     < x

The missing step is add 8x to both sides of the inequality.</u>
