-7/4
Because where the next point meets is 7 across and 4 down. And since the line is going down then the slope is negative
When Determining positive and negative I like to think of it like I’m writing my name on the line, if my name goes down the line then it’s negative, but if my name is going up then it’s positive.
I hope this helps
I think it was subtract. Im confuse too but it said much, so i think it was subtract
Let m <1 = x then
x = 2(90 - x)
x = 180 - 2x
3x = 180
x = 60
M <1 = 60 and m < 2 = 30 degrees answer
Draw a radius of 90 degrees on a Triangle retangle of ABC
First, find the radius

r=9 cm
Now, we can just use the circle area formula to solve
