Answer:

EH ≈ 2.67

Step-by-step explanation:

In this geometry, all of the right triangles are similar. This means corresponding sides are proportional:

short side / long side = EH/FH = FH/GH

EH = FH²/GH = 4²/6 = 2 2/3

EH ≈ 2.67

Two identical triangles form a parallelogram with a base of 8 Inches and a height of 6 inches.What is the area of one triangle?

dedylja [7]

Answer: The area of the triangle is 24 square inches

Step-by-step explanation:

Hi, since the 2 triangles form a parallelogram ( see attachment) we have the base and height of the triangles, we have to apply the next formula:

Area of a triangle; (base x height) /2

Replacing with the values:

A = (8x6 )/2

A = 48 /2

A = 24 square inches

The area of the triangle is 24 inches

Feel free to ask for more if needed or if you did not understand something.

Chip has used 23 of the bricks he originally had for putting brick on the house he is building. He has 1,200 bricks left. How ma

vlabodo [156]

The number of bricks he originally has is 1800

<h3>How to determine the number of bricks he originally has?</h3>

From the question, we have the following parameters that can be used in our computation:

Bricks used = 2/3 of the bricks he originally

Bricks left = 1200

Since he used 2/3 of the bricks, then he has 1/3 bricks left

This can be represented using the following equation

Bricks left = Proportion of bricks left * Total number of bricks

Substitute the known values in the above equation, so, we have the following representation

2/3 * Total number of bricks = 1200

Multiply both sides by 3/2

Total number of bricks = 1800

Hence, the total number of bricks is 1800
