Answer:
Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2).
Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).
Step-by-step explanation:
The variables have to be the same in both equations in the 2 × 2 system.
All of this should be included

x= 33.9
Step-by-step explanation:
use cosine because x is the adjacent and 40 is the hypotenuse
set up your equation:
cos(32)= (x/40)
multiply both sides by 40:
40(cos(32))= (x/40)40
40(cos(32))= x
multiply 40 by the cos(32):
33.9 = x

Step-by-step explanation:

Answer:
5° is the difference
Step-by-step explanation:
One of the ramps is 5° and the other one is 10°. The difference between these 2 ramps is of 5°.
10 - 5 = 5
And as you can see in the image, the mid ray is what divided both of the other rays, and its right in the middle. Both rays combined gives you 10° as it shows, and half of 10 is 5. So the difference will be of 5°

Answer:
57.8º
Step-by-step explanation:
According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
