What's two thirds of a straight line?
Komok [63]
Well if the straight line is equal to 1 then your answer is 2/3 but if the straight line is not equal to 1 you need to know what it is equal to or you could use the equation y = (2/3)x
"x" would be the length of the straight line and "y" would be two-thirds of it

HELP A triangle and its angle measures are shown in the diagram. What is the value of x?
Stolb23 [73]

Answer:

a. 16

Step-by-step explanation:

Triangles = 180 degrees

180 - 80 = 100

100 = (4x - 4) + (0.5x + 32)

4x - 4 + 0.5x + 32 =100

(4x + 0.5x) +(-4 + 32) = 100

4.5x + 28 = 100

4.5x + 28 -28 = 100 - 28

4.5x = 72

4.5x/4.5 = 72/4.5

x = 16
