Answer:
The measure of each angle is 143 degrees.
Step-by-step explanation:
We are given the following in the question:
A nonagon in which measure of seven angles are:
138, 154, 145, 132, 128, 147, 130.
Angle sum property of a nonagon:
- The sum of interior angles if a nonagon are 1260 degrees.
Let the two equal angle of nonagon be x degrees. Thus, we can write:
Thus, the measure of two equal angles is 143 degrees.
Answer:
a. $1000
b. 100
c. 900
d. 1017
Step-by-step explanation:
a.
marked price = 800×1.25=1000
b.
discount amount
1000×0.9=900
1000-900=100
c.
1000×0.9=900
d.
900×1.13=1017
Answer:
= 3/4
Step-by-step explanation:
WX = 9
W = 12
12X = 9
Divide both sides by 12
12X/12 = 9/12
X = 9/12 - Simplify
X = 3/4
X is located at 3/4
