Answer: h=12.8in

a Base edge 15 in

V Volume 960 in³

Using the formula

V=a2h

Solving for h

h=3V

a2=3·960

152=12.8in

If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)

Sphinxa [80]

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56

the measure of ∠D is 5 times the measure of ∠E the two angles are supplemanty find the measure of each angle

hammer [34]

Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing $\frac{180}{6}$ which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180
