6. Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale.
x = 160, because 180 - (130+30) = 20 and 180 - 20 = 160

60°
x = 80, because 180 - 130 = 50 and 50 + 30 = 80

120°
x = 20, because 130 + 30 = 160 and 180 - 160 = 20
x = 340, because 130 + 30 = 160 and 160 + 180 = 340

Based on these triangles, which statement about x is true?

x = 160, because 180 - (130 + 30) = 20 and 180 - 20 = 160

Step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
