Answer:

Step-by-step explanation:

using Triangle Proportionality theorem, it states that if a constructed line parallel at one side of a triangle intersects the other two sides of the triangle and divides the remaining two sides proportionally; meaning

10:3x-5 = 8:28

<h2><u>10</u>    =   <u>8</u></h2><h2>3x-5     20</h2><h2>cross multiply</h2><h2>10 x 20 = 8(3x-5)</h2><h2>200 = 24x - 40</h2><h2>add 40 to both sides</h2><h2>200 + 40 = 24x - 40 + 40</h2><h2>240 = 24x</h2><h2>divide both sides by 24</h2><h2>240/24 = x</h2><h2>10 = x</h2><h2></h2><h2>b. perimeter is side + side + base</h2><h2>{10+(3x-5)} + {16} + {28}</h2><h2>since x =10</h2><h2>10+(3(10)-5)</h2><h2>10+30-5</h2><h2>40-5=35</h2><h2>35+16+28=79</h2>

1. What is the formula for Pythagorean Theorem
Debora [2.8K]

Answer:

The formula is a^2 + b^2 = c^2

Step-by-step explanation:

A and B are legs and C is the hypothunisis.

The theorem is used for triangles.

4^2  + 5^2 = c^2

16 + 25 = c^2

41 = c^2

sqr(41) = sqr(c)^2

Gerry arrived at the bus stop x hours past noon. Dale arrived 4 hours later. Pat arrived at 5 P.M., x hours after Dale.
victus00 [196]

Answer:

<em>Gerry arrived at the bus station at 12:30 P.M.</em>

Step-by-step explanation:

From noon and 5:00 P.M. there are 5 hours.

Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.

4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.

If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:

Gerry arrived at the bus station at 12:30 P.M.

Dale arrived at the bus station at 4:30 P.M.

Pat arrived at the bus station at 5:00 P.M.
