For this you can work is doing it in a diagram.
Given:
Perimeter of the triangle = 99 ft
Length of two sides are 20 ft and 42 ft.
To find:
The length of missing side.
Solution:
Let the missing side be x.
Perimeter of a triangle is the sum of all sides of that triangle.
Subtract 62 from both sides.
Therefore, the missing side of the triangle is 37 ft.
Answer:
x=9
Step-by-step explanation:
90(the angle)-30=60
60-15=45
45/5=9
<u>(5(9)+15)+30=90</u>
Answer:
70 m^2.
Step-by-step explanation:
Area of the triangle = 1/2 * base * height.
Counting the squares on the coordinate plane:
Base = 7, height = 5
Each square = 2 meters
So the area = 1/2 * 14 * 10
= 70m
The answer to this question is 5/25 five out of twenty five will be yellow.
