<h3>First let us know –</h3>
- What is complementary angle ?
When sum of two angles is 90°, then each of those two angles will be considered to be the complementary angle of each other.<u>Example</u> : 60° and 30° are two angles, and their sum is 90°. So, 60° and 30° are complementary angles.
____________________
<h3><u>Explanation</u> :-</h3>
- Measure of an angle is 13.8° more than the measure of it's complementary angle. We are asked to find measure of each angle!
<h3><u>Solution</u> :-</h3>
- One of the complementary angles be "x" . Then the other angle becomes " (x + 13.8)° "
- Sum of these two angles is equal to 90° . Since they are complementary angles.
<u>Then</u> –
- The measures of the two given angles is 38.1° and 51.9°.

To have a width of 3.5 ft we have to divide 10.5 by 3
If we do the same and divide 12 by 3 we get 4ft length
so the area of the scale model is 3.5 * 4 = 14 ft

Hello Charlesbabegirl! :)
Hope you're having a nice day!
First of all, let's say that the sum of all internal angles of a triangle is always 180°
This means that if you add up angles A, B and C you get 180 but we should find first the value of x by setting up a proportion of this type:
A + B + C = 180
48 + 6x - 28 + 2x = 180
Move all the known terms (those that don't have x) to the right with changed sign.
6x + 2x = 180 - 48 + 28
8x = 160
Divide both terms by 8
x = 20
Then plug the value of x...
m∠B = 6(20) - 28 = 120-28 = 92°
m∠C = 2(20) = 40°
Hope I helped and let me know if I was right!
