Answer:
120°
Step-by-step explanation:
X= 55 degrees ...........
Answer for 1st set:
m∠1=105° and m∠2=75°
Breakdown:
You're given one angle of 75°. That one angle is equal to m∠2. Since m∠2 is making a linear pair with m∠1, you take 180° (Straight line) and take 75° from it.
180-75=105
Answer for 2nd set:
m∠1=130° and m∠2=50°
Breakdown:
Using the same logic as before, linear pair, blah-blah-blah, you're given 130.
180-130=50
4.2 because millimeters are in the decimals section you just add 9 to 3
9+3=12
=4.2
Hello! Slope is rise/run. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the first x and y-coordinates from the second x and y-coordinates. We have the points (-2, -3) (first) and (4, 0) (second). Let's find what the numbers represent and then solve.
y2: 0
y1: -3
x2: 4
x1: -2
It becomes set up as 0 - (-3) / 4 - (-2). 0 - (-3) is 3. 4 - (-2) is 6. Keep in minid that when you subtract a negative number, you are actually adding. 3/6 is 1/2 in simplest form. There. The slope is 1/2.
