Determine the measure of each indicated angle. Show all necessary steps!
1 answer:
The measure of the unknown angle are; a) x = 89 degrees, b) p = 92 degrees.
<h3>What is the sum of all the angles of a regular polygon?</h3>
For a regular polygon of any number of sides, the sum of its exterior angle is 360°.
We already know that a 4-sided polygon's angles add up to 360 degrees.
So to find the value of x:
69 + 118 + 84 + x = 360
x = 360 - (69 + 118 + 84)
x = 89 degrees
b)
For a 4-sided polygon, we also know that the outside angles add up to 360 degrees.
So to find the value of p:
100 + 62 + 106 + p = 360
p = 360 - (100 + 62 + 106)
p = 92 degrees

Answer:
The number of apples bought was 7 and the number of pears bought was 4
Step-by-step explanation:
<u><em>The correct question is</em></u>
Thanh bought 11 pieces of fruit and spent $5.60. If apples cost $0.60 each and pears cost $0.35 each, how many of each kind of fruit did he buy?
Let
x ---->the number of apples bought
y ----> the number of pears bought
we know that
Thanh bought 11 pieces of fruit
so
----> equation A
apples cost $0.60 each and pears cost $0.35 each and Thanh spent $5.60
so
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (7,4)
see the attached figure
therefore
The number of apples bought was 7 and the number of pears bought was 4
