Answer/Step-by-step explanation:
a. m<h = x°
Two angles to use in finding x are <h and 55°
Angle pair formed: linear pair angles
b. x° + 55° = 180° (linear pair)
Subtract 55° from each side
x + 55 - 55 = 180 - 55
x = 125°
c. Given: m<n = y°
Two angles to use in solving for y are: <h and <n
Angle pair formed: alternate exterior angles
d. m<n = y° (given)
m<n = x° = 125° (as solved in 2b)
Therefore:
y = x (alternate exterior angles are congruent)
thus:
y = 125° (substitution)
D i think but not really sure maybe idk
Answer:
![\left[\begin{array}{ccc} -10 & -9 \\ -8 & -2 \\ -11 & 67 \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%20-10%20%26%20-9%20%5C%5C%20-8%20%26%20-2%20%5C%5C%20-11%20%26%2067%20%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
This is a matrices. Since they are both the same in format, we can add them together. But first we must multiply each value by the given values.
1.
![\left[\begin{array}{ccc}-30 & -5 \\ 20 & 30 \\ -35 & 35 \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-30%20%26%20-5%20%5C%5C%2020%20%26%2030%20%5C%5C%20-35%20%20%26%2035%20%5Cend%7Barray%7D%5Cright%5D)
