<h2>
Answer:</h2>
First we must find the opposite-reciprocal of the original slope.
current slope: 
new slope: 
Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.
The y-intercept is 
.
Now, we can write the formula for the new line.
Slope-intercept form: 
Point-slope form: 
Answer:
cos(m∠B) = 2√5/5
Step-by-step explanation:
Easiest way is to guess and check on this problem. When you take the cos(m∠B), you would get 6/3√5, rationalized to 2√5/5. That would be the correct answer.
Angle 45
Because it could be 45,45,90
Answer: 21.5cm³
Step-by-step explanation: This is your answer there is no way it is incorrect
Answer:
4.21, 4.22, 4.23,
4.24 (choose any one)
Step-by-step explanation:
since 4 1/5 is 4.20, so the numbers in between 4.20 and 4.25 are 4.21, 4.22, 4.23,
4.24 (choose any one)
