Answer:
= 3 3/4 m^2
or 15/4 m^2
Step-by-step explanation:
The base is the triangle.
A =1/2 bh
A = 1/2 (3 1/3 * 9/4)
Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3
A = 1/2 * 10/3 *9/4
Re arranging
= 1/2* 9/3 * 10/4
= 1/2 (3) 5/2
=15/4
Now writing as a mixed number
= 3 3/4 m^2

Answer:
It was used as scale factor.
Step-by-step explanation:
The scale factor is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are of different sizes.
To find the scale factor that was used when going from the grey triangle to the yellow triangle we can work with any of the three sides of the grey triangle.
Let's work with the below side.
The below side is extended from the point to the point
The length of this side is 9 units.
In the yellow triangle, we can see that the below side is extended from the point to the point
The length of this side is 3 units.
Working with the lengths and the scale factor ⇒
We find that the scale factor that was used when going from the grey triangle to the yellow triangle is

Answer:
Option C is correct.
is the angle supplementary to the angle measuring
Step-by-step explanation:
To find the angle supplementary to the angle measuring
Let A be the angle supplementary to the angle measuring .
Supplementary Angles states that the two Angles are Supplementary when they add up to 180 degrees.
Use the conversion:
1 degree = 60 minute.
Then, we have the given angle =
Now, by definition of supplementary angle;
Subtract 165.2 on both sides we get;
Therefore, the angle supplementary to the angle measuring is,
