The value of r is -24
Step-by-step explanation:
Given points are:
(1,r) and (5,-4)
Let the points be:
(x1,y1) = (1,r)
(x2,y2) = (5,-4)
m = 5
The slope is given by:
Hence,
The value of r is -24

Answer:15
Step-by-step explanation:
Answer:
x = 31
Step-by-step explanation:
The perimeter is the sum of the equal-length sides:
63 = (x -10) +(x -10) +(x -10)
63 = 3x -30 . . . . . . . . collect terms
21 = x -10 . . . . . . . . . . divide by 3
31 = x . . . . . . . . . . . . . add 10
Answer:
angle 7 is 26 degrees
Step-by-step explanation:
180 - 154 = 26
So hmm notice the first picture, that's the "inscribed angle theorem", as you'd know
now, notice angle 2 in yours on the second picture
