Answer:
55
Step-by-step explanation:
Because the base is a straight line, each of the unknown angles in the triangle are 180 - 2h. This means that 360 - 4h + 40 = 180, so 400 - 4h = 180.
Now subtract -4h + 180 from both sides to get 220 = 4h so h = 55.

The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.
<h3>How do we derive a numerical expression?</h3>
Let:
x = amount of time it takes Imani to walk to school
y = amount of time it takes Imani to ride to school = 3 minutes
The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:
x = 5y - 1
Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:
x = (5 * 3) - 1 = 15 - 1 = 14 minutes

Straight line: supplementary
Supplementary is sum of 180 degrees
x + 96 + 5x = 180 degrees
6x + 96 = 180
6x = 84, x = 14
Solution: x = 14
