Answer:
42°
Step-by-step explanation:
angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°
Answer:
A)
0

It is zero.
0= 54r
Therefore r=0.
Answer:
3x -y = 6
Step-by-step explanation:
When the equation of a line is given in the form ax+by=c, the perpendicular line through point (h, k) will be ...
bx -ay = bh -ak
Here, we have a=1, b=3, h=1, k=-3, so the line is ...
3x -y = 3(1) -(1(-3))
3x -y = 6
Answer: There are 
children at the circus show.
Step-by-step explanation:
Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.
Knowing that 
of the spectators are men, we can find the remaining:
Since 
of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:
Solving for "x", we get:
Therefore, we get that "c" is:
Answer:
A. P=11*3 = 33 ft
A= 21*3 = 63 ft^3
B. P = 9*3 = 27 ft
A = 15*3 = 45 ft^3
C. P = 20*3 = 60 ft
A = 24*3 = 72 ft^3
D. P = 13*3 = 39 ft
A = 25*3 = 75 ft^3
Step-by-step explanation:
