The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement
We have the following equation:
90+156+28+x=360
x=360-90-156-28
x=86
Answer: the size of the 4th angle would be 86º.

Step-by-step explanation:
Circumference=72
pi=3.14
Radius=C
/2π
72/6.28=11.4649681529
Rounded to the whole would be 11
=11
Answer:
c
Step-by-step explanation:
The answer is $6.80.
The full price: $8.00 (100%)
The discount: 15%
The discounted price: x (100% - 15% = 85%)
Make a proportion.
$8.00 : 100% = x : 85%
x = $8.00 * 85% : 100% = $6.80
