Answer:
y = 5.5
Step-by-step explanation:
The total distance between the lines j and l is 10.
The total distance between the lines k and l is 9.
To find the distance between the lines j and k we can use the given information.
10 (distance between j and l) - 9 (distance between k and l) = 1 (the distance between the lines j and k).
So the distance between lines j and k is 1.
In the given picture the distance is shown as 2y-10.
This means 2y - 10 = 1
Now we need to solve this equation to find y.
2y - 10 = 1
2y = 1 + 10
2y = 11
y = 11/2
y = 5.5
(NOTE: We are not including 4 in the process of finding the value of y because this particular line is not similar to the line where y is )
The answer is B: 2.4! hope this helped...
Answer: Measure angle H = 42°
Step-by-step explanation:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"
In given we have,
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H
Based on the above rule,
measure angle E = measure angle D + measure angle H
We are given this:
angle E = 87°
angle D = 45°
Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°
Hope this helped!
Answer:
I cannot see it well
Step-by-step explanation:
Given :
Length of one of the equal sides of an isosceles triangle = 3x+2
Then, length of the other equal side will also be = 3x+2
Length of the unequal side of this isosceles triangle = 14
Formula for finding the perimeter of an isosceles triangle :
A formula for finding the perimeter of this isosceles triangle :
Bringing all like terms together we get :
Thus, the formula = 6x+18
Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
