Answer:
A
Step-by-step explanation:
well some people like to go on a budget and others prefer not to because they rather spend their money money on wants rather than needs so I really hope this helps.
Based on the definition of complementary angles, the two angles are: 49.4° and 40.6°.
<h3>What are Complementary Angles?</h3>
Angles that are complementary angles have a sum of 90 degrees.
Let the angle be represented as x
Complement of the angle = (90 - x)
Therefore, we would have:
x = (90 - x) + 8.8
x = 90 - x + 8.8
x = 98.8 - x
x + x = 98.8
2x = 98.8
x = 98.8/2
x = 49.4°
The second angle would be: 90 - 49.4 = 40.6°
The angles are 49.4° and 40.6°.

Answer:
The other sides of triangles are 8.72 in and 8.72 in
Step-by-step explanation:
In a triangle ABC. Please find the attachment for figure.
![\angle A=70^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20A%3D70%5E%7B%5Ccirc%7D)
![\angle B=\angle C=55^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20B%3D%5Cangle%20C%3D55%5E%7B%5Ccirc%7D)
Side BC=a = 10 in
Using sine law of trigonometry,
![\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}](https://tex.z-dn.net/?f=%5Cdfrac%7Ba%7D%7B%5Csin%20A%7D%3D%5Cdfrac%7Bb%7D%7B%5Csin%20B%7D%3D%5Cdfrac%7Bc%7D%7B%5Csin%20C%7D)
Substitute the given value into formula.
![\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}=\dfrac{c}{\sin 55}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B%5Csin%2070%7D%3D%5Cdfrac%7Bb%7D%7B%5Csin%2055%7D%3D%5Cdfrac%7Bc%7D%7B%5Csin%2055%7D)
![\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B%5Csin%2070%7D%3D%5Cdfrac%7Bb%7D%7B%5Csin%2055%7D)
Cross multiply and we get
![b=\sin 55\times \dfrac{10}{\sin 70}](https://tex.z-dn.net/?f=b%3D%5Csin%2055%5Ctimes%20%5Cdfrac%7B10%7D%7B%5Csin%2070%7D)
in
It is a isosceles triangle. Therefore, b=c=8.72 in
Hence, The other sides of triangles are 8.72 in and 8.72 in
Answer:
measure is the angle right- if so it's 76 each
180-28=152
152÷2=76
