Answer:
y = -5x-4
Step-by-step explanation:
start with slope-intercept form:
-9-11/1+3 = -20/4 = -5
your slope is -5
next, do point-slope form:
y+9 = -5(x-1)
y+9 = -5x+5
-9 -9
y = -5x-4
Knowing that all triangles angles add up to 180*:
24* + x + ? = 180*
Knowing the straight line is 180*:
180* - 122* = 58*
The equation then is:
24* + x + 58* = 180*
Then solve for X:
(82* + x) - 82* = (180*) - 82*
<u>x = 98* or C</u>
The correct answer to your question would be C, to list the the product as 2 for 6$
Octagon = 8-side polygon
<u>Find area of 1 triangle:</u>
Area of one side triangle = 60 ÷ 8 = 7.5 m²
<u>Given area and length, find height:</u>
Area of each triangle = 7.6 m²
Length of each triangle = 3m
Area = 1/2 x base x height
7.5 = 1/2 x 3 x height
Heigth = 5m
Answer: Slanted Height = 5 m
