Answer:

Step-by-step explanation:
Use the formula
to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (
).
So, we can setup an equation:

Solve for z:
Combine like terms
Subtract 200
Divide by 5
Therefore, the value of z = 68.
Answer:
2.0
Step-by-step explanation:
To round 1.961 to the nearest tenth consider the hundredths’ value of 1.961, which is 6 and equal or more than 5. Therefore, the tenths value of 1.961 increases by 1 to 0.
1.961 rounded to the nearest tenth = 2.0

a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
the constant of proportionality is k, so k=-5
Answer:
30 in
Step-by-step explanation:
Answer:
20 units.
Step-by-step explanation:
To find the perimeter of a trapezoid, the formula is a + b + c + d
a = 1
b = 9
c = 5
d = 5
So, the perimeter is 20 units.
