Answer:
10 inches
Step-by-step explanation:
Given
Shape: Isosceles Triangle


Required
Find the length of the other two sides
Represent the other sides with x.
Since it is an isosceles triangle, 2 sides are equal.
So, we have:


Collect Like Terms


Divide both sides by 2



<em>The other sides are 10in each</em>
For this case, the first thing we must do is define a variable.
We have then:
p: rate in miles per hour for the last 1.5 hours
We now write the equation that models the problem.
We have then:

Rewriting we have:

From here, we clear the value of p.
We have then:
Answer:
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour.
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
Answer:
v = 8
Step-by-step explanation:
-v -7-3 = -26+v
2v = -10+26
2v = 16
v = 8
