Answer:
m = 3/2
Step-by-step explanation:
The slope of a line is m = rise / run.
As we move from P to Q, x increases from -8 to -5 (3 units) and y decreases from -10 to -12 (2 units). Hence, the slope of this line is m = rise / run
and m = -2 / 3.
Any line perpendicular to this line has a slope which is the negative reciprocal of this.
(slope of perpendicular line) = -1 / (-2/3) = 3/2
Answer:
x = 20°, y = 70° see image
Step-by-step explanation:
Use the bottom, lower, short wide triangle first. It has marks on it to show that two of the sides are the same length. That means that the opposite angles are the same. One is marked x, so the other is also x. There is a 40° angle given, along the same line right next to it has to be 140°. We'll use that one.
Also, the angles in a triangle add up to 180°.
x° + x° + 140° = 180°
See image for calculations.
Then we use the whole entire triangle. It has a 90° angle and the 20° (for x, that we just found) and y. We'll use that to find y.
90° + y + 20° = 180°
See image for calculations.
