<span>Triangle PQR is a right triangle. First we have to find the length of each side of the triangle. This can be done using the points provided, along with the Pythagorean theorem, which is a^2+b^2=c^2.
PR^2 = (7- -2)^2+(3-5)^2 = 85 => PR = sqrt(85)
QR^2 = (7- -1)^2+(3-1)^2 = 68 => QR = sqrt(68)
QP^2 = (1-5)^2+(-1 - -2)^2 =17 => QP = sqrt(17)
Now that we have the sides of the triangle, we can put them into the Pythagorean theorem again to see that it works out:
(Sqrt(17))^2 + (sqrt(68))^2 = (sqrt(85))^2
17 + 68 = 85
85 = 85
Since the Pythagorean theorem works for right triangles, the triangle is indeed a right triangle.</span>
First, find the slope of the line segment connecting the 2 given points:
10-(-2) 12
m = ----------- = --------- = 3
3-(-1) 4
Use the point-slope form: y-(-2) = 3(x-[-1]), or y = 2 + 3x - 3, or y = 3x - 1
Can you now fill in the blanks properly?
Answer:
x=119 and x=80
Step-by-step explanation: a triangle always equals to 180
x+61=180
x+61-61=180-61
x=119
x+100=180
x+100-100=180-100
x=80
