ACB = AC + BC
ACB = 122 + 192 = 314
The answer is b. 314 degrees
Draw a right triangle (attachment below):
Length of the vertical line = 6 units
Length of horizontal line = 8 units
a^2 + b^2 = c^2
6^2 + 8^2 = 100
Square root of 100 = 10
The distance between the two points is 10 units.
Answer:
B
Step-by-step explanation:
use the slope formula to find the slope. y2-y1/x2-x1. 3-(-6)/-4-2 which is 9/-6 (subtracting a negative number is the same as adding a positive) which can be simplified to -3/2 which is the slope. the intercept is the point where y is at x=0, we already know at y=3 x is -4 from the second point, so the y intercept has to be -3. which can be proven by replacing the x and y with a point 3 = -3/2(-4) - 3. put -3/2 times 4 into a calculator and you get 6, 6-3 is 3 which makes the statement true.
Bbbbb cye oooooooooooooooooooooooooo
