Answer:
area of trapezium:
a+b divided by 2, times by the height.
so its 8+20=28.
28/2=14.
14*14=196.
area=196
Step-by-step explanation:
It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6
Answer:
The equation is y = -5/6 x-4
Step-by-step explanation:
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -5/6 x+b
Substitute in the point
-9 = -5/6(6) +b
-9 = -5+b
Add 5 to each side
-4 = b
The equation is y = -5/6 x-4
