Answer:
25 feet
Step-by-step explanation:
x^2= 20^2+15^2
x ^2 = 400 + 225
x ^2 = 625
x^2= √625
x= 25
94%
47/50 × 100 = 47 ×2 = 94 %
20 weeks, earnings $(15 + 35), spending $300:
<span>20(15 + 35) - 300 = amount of money she has left
</span>
The common denominator would be 15 since 5 times 3=15.
We can find x only if we know that the figure is a REGULAR octagon, i.e. an octagon with all sides equal, and all interior angles equal.
We will ASSUME that the figure is a regular octagon.
For a regular polygon, the central angle subtended by each side is equal.
The central angle is 360 degrees.
So the central angle subtended by a single side euqals
a=360 degrees / 8 sides = 45 degrees / side
Since x is the total angle subtended by three sides, so
x=3*45=135 °
