Answer:
Step-by-step explanation:
Using the pythagorean theorem, a^2+b^2=c^2
32/2=16, 20 would be the hypotenuse, so it would be 20^2-16^2=a^2 because we want to find the middle line. 400-256=144. sqrt(144) = 12.
Then since it is an isosceles triangle, we can simply do 12*16=192
The answer for 7 is 192ft^2
For #8, the answer is short leg * sqrt(3) = long leg
On another note, you can find the hypotenuse of a 30-60-90 triangle by doubling the shortest leg
Answers number 4 and 6. aka (0,-7) and (0,-0.25) :)
Answer:
y=3x+1
Step-by-step explanation:
Determine slope with two coordinates and use it in the formula
This is a slope equation. the 2x is your slope (rise over run) and your 3 is your y-intercept. So to graph you put positive 3 on your y axis and with your 2x you rise 2 run one. I hope i helped
