Answer:
A= 30
B= 60
C= 90
Step-by-step explanation:
A is already shown.
B has a right angle making it 90 degrees.
A triangle is 180 degrees 30+90= 120
180-120=60
For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.
For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.
Answer:
L = 2W, and LW = 5000. Therefore 2W^2 = 5000, so W^2 = 2500. This means W=50 and L=100.
Step-by-step explanation:
The solution of given inequality is: 
<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>

We have to find the value of "x"
<em><u>Let us solve the given inequality</u></em>
Divide both sides of inequality by 7

<em><u>Simplify the above expression</u></em>




Thus the value of x is
