1. given the triangle below, answer the following questionsa. what is the value of x? b. what is the value of y? c. what is the value of z? show your work.

x=81

y=99

z= 129

Step-by-step explanation:

the 3 angles of a triangle add to 180 degrees

51 + 48 + x = 180

99 + x = 180

subtract 99 from each side

99 + x -99 = 180 -99

x = 81

x+y = 180  they make a straight line

81+ y = 180

subtract 81 from each side

y = 180-81

y = 99

z+ 51 = 180  they make a straight line

subtract 51 from each side

z+51-51 = 180 -51

z = 129

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
