To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5

The measure of angle x is 25 more than 4 times the measure of its complement. Find the measure of x.
topjm [15]
- Two angles that are complements of each other add to equal 90 degrees (they are complementary angles). 
- One angle measures x degrees.
- The other angle measures 25 more than 4 times the angle that measures x degrees; it measures 4x + 25 degrees.

To find x, set the sum of these expressions (x and 4x + 25) equal to 90 and solve algebraically for x.

90 = x + (4x + 25)
90 = x + 4x + 25
90 = 5x + 25
65 = 5x
13 = x

If you wanted to find the measure of angle x, you'd substitute 13 for x in its expression, 4x + 25.

4x + 25
4(13) + 25
52 + 25

Answer:
x = 13

(09.05 MC) Derek kicks a soccer ball off the ground and in the air, with an initial velocity of 31 feet per second. Using the fo
ivann1987 [24]
In order to find the maximum of the function, we have to find the roots of the first derivative. 
H(t)=-16t^2+vt+s\\ H'(t)=-32t+v=0\\ v=32t\\ t=\frac{v}{32}=\frac{31}{32}=0.97s
This gives us the time at which the ball reaches its maximum height. 
We don't know s. We can find it because we know that at t=0 the ball is on the ground and its height has to be zero.
H(0)=0=-16(0)^2+v(0)+s\\ s=0
Finally, we can find the maximum height:
H(0.97)=-16(0.97)^2+31\cdot 0.97=15.0156 \simeq15$ft
The answer is C.
