- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
x + (x + 65) + 25 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 90 = 180
- Isolate <em>x</em> term: 2x = 90
- Isolate <em>x</em>: x = 45
It's a percent decrease and it decreases by -50%
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
