Answer:
1 3/4 = 7/4 = 1.75
Step-by-step explanation:
The process to arrive to the solution is explained in the pictures below.
Tyler needed to convert the mixed fraction
2 1/2 = (4+1)/2 = 5/2
If we multiply by 2 numerator and denominator
5*2/2*2 = 10/4
We substract
10/4 - 3/4 = 7/4 = 1.75

The sum of the angles in the triangle must be equals to 180 degrees for it to be the angle measure of a triangle.
<h3>Angles in a triangle</h3>
The sum of angles in a triangle is equals to 180 degrees.
Therefore, adding up the three angles in a triangle must be equals to 180 degrees.
Hence,
42 + 34 + 56 = 132 degrees
This does not form a triangle.
35 + 80 + 65 = 180 degrees
This can be the angle measure of a triangle.
15 + 51 + 24 = 90 degrees
This cannot be the angle measure of a triangle.
18 + 42 + 120 = 180
This can be the angle measure of a triangle.

Answer:
Step-by-step explanation:
<h3>Method 1</h3>
<u>Area of trapezium</u>
- A = 1/2(b1 + b2)h
- A = 1/2(3 + 7)(4) = 1/2(10)(4) = 20 unit²
<h3>Method 2</h3>
<u>Area of rectangle - Area of triangle</u>
- A = lw = 7*4 = 28 unit²
- A = 1/2bh = 1/2*4*4 = 8 unit²
- 28 - 8 = 20 unit²
