Step-by-step explanation:
The sum of the three angles in a triangle must be
. Since this triangle has a right angle, we know that it is
°, so the sum of the remaining two angles must be
.
We can set up an equation for the two remaining angles to determine the value of
:
![(x + 28) + x = 90](https://tex.z-dn.net/?f=%28x%20%2B%2028%29%20%2B%20x%20%3D%2090)
![2x + 28 = 90](https://tex.z-dn.net/?f=2x%20%2B%2028%20%3D%2090)
![2x = 62](https://tex.z-dn.net/?f=2x%20%3D%2062)
![x = 31](https://tex.z-dn.net/?f=x%20%3D%2031)
x/2 = -0.73
To solve for x multiply both sides by 2:
x = -1.46

Answer:
<h3>C. (a, b)</h3>
Step-by-step explanation:
The formula of a midpoint:
![M\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)](https://tex.z-dn.net/?f=M%5Cleft%28%5Cdfrac%7Bx_1%2Bx_2%7D%7B2%7D%3B%5C%20%5Cdfrac%7By_1%2By_2%7D%7B2%7D%5Cright%29)
We have A(0, 0) and C(2a, 2b). Substitute:
![x=\dfrac{0+2a}{2}=\dfrac{2a}{2}=a\\\\y=\dfrac{2b+0}{2}=\dfrac{2b}{2}=b](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B0%2B2a%7D%7B2%7D%3D%5Cdfrac%7B2a%7D%7B2%7D%3Da%5C%5C%5C%5Cy%3D%5Cdfrac%7B2b%2B0%7D%7B2%7D%3D%5Cdfrac%7B2b%7D%7B2%7D%3Db)
M(a, b)
