Mark Brainliest if correct:
x = 36
Step-by-step explanation:
x + 2x + 3x + 4x + 5x = 540 (Sum of interior angles in pentagon)
15x = 540
x = 36
15 rounded to the nearest hundred is 100 or one hundred
Answer:
the length of one side is 120
Step-by-step explanation:
let the length = x
we need to form an equation to find the side...
since its 10 per metre
10x = 1200
x = 1200/10
x=120

Answer:
Step-by-step explanation:
Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.

The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
