Answer:
x = -7, A = 65 degrees
Step-by-step explanation:
[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]
Therefore,
x + 72 + x + 51 + 71 = 180
2x + 194 = 180 [collect like terms]
2x = -14 [subtract 194 from both sides]
x = -7 [divide both sides by 2]
To find A, we substitute the value of x into x + 72:
A = (-7) + 72
A = 65 degrees.
Hope this helps! :D

Answer:
y = 3/2 * x + 12
Step-by-step explanati
2x + 3y = 12
y = -2/3x + 4
slope: -2/3
slope' of perpendicular line: 3/2
6 = 3/2 * (-4) + b
b = 12
equation: y = 3/2 * x + 12
Answer:
Step-by-step explanation:
Given
Required
Write an equation to determine the payment at a given week
At week 1, she'd have paid $8
At week 2, $16
Week 3, $24
..
.
This leads to arithmetic progression (AP):
8, 16, 24.....
To further solve, we'll make use of AP formula
In this case;
So, the equation becomes
Collect Like Terms
The above represents the amount paid at a particular week;
Amount owed, L is then calculated as follows;
