Answer:
42, 138, 138
Step-by-step explanation:
the line not adjacent to the 42 degree angle is also 42 by the vertical angles theorem. Then you find the measure of the other 2 by x+42=180 so x=138.
The answer is n^3×2^(n+1)
Answer:
80
Step-by-step explanation:
Answer:
y=8x-23
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is 8, m=8.
subst. m=8 into the equation:
y= 8x +c
To find c, substitute a coordinate.
When x=3, y= 1,
1= 8(3) +c
1= 24 +c
c= 1 -24
c= -23
Thus, the equation of the line is y= 8x -23.
