Tan 37,4 = opposite/adjacent
tan 37,4 = x/12,8
• then multiply both sides by 12,8
12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)
Second one:
Answer:
y=4
x=61
Step-by-step explanation:
the 2 lines on the side shows that they are equal to each other.
12y+3=51
12y=48
y=48/12
y=4
There are 100 degrees in a triangle and the little curve shows that the angle next to 53 degrees is 63.
so:
x+56+63=180
x+119=180
x=61
Triangles ABC and QRS are congruent.
Both of them are 4 units wide and 3 units top-to-bottom.
Triangle DEF is not the same size and shape as any other triangle,
and neither is triangle XYZ.
p=8h is the equation which shows the total pay is 8 times the number of hours worked.
Mario's:
8 * 14.13 = 113.04
A = pi * r^2
Plug in what we know:
113.04 = 3.14 * r^2
Divide 3.14 to both sides:
36 = r^2
Find the square root of both sides:
r = 6
Plug this into the formula for the Circumference of a Circle:
C = 2 * pi * r
C = 2 * 3.14 * 6
Multiply:
C = 37.68
Tito's:
16 * 12.56 = 200.96
A = pi * r^2
Plug in what we know:
200.96 = 3.14 * r^2
Divide 3.14 to both sides:
64 = r^2
Find the square root of both sides:
r = 8
Plug this into the formula for the Circumference of a Circle:
C = 2 * pi * r
C = 2 * 3.14 * 8
Multiply:
C = 50.24
Peter's:
10 * 15.386 = 153.86
A = pi * r^2
Plug in what we know:
153.86 = 3.14 * r^2
Divide 3.14 to both sides:
49 = r^2
Find the square root of both sides:
r = 7
Plug this into the formula for the Circumference of a Circle:
C = 2 * pi * r
C = 2 * 3.14 * 7
Multiply:
C = 43.96
So the correct order is:
Mario's, Peter's, Tito's
