Answer:
3 m^2
Step-by-step explanation:
The shaded area = Area of Sector - Area of Triangle
First we find area of sector =
<em>We know the angle is 60° (vertical angles are equal) and the radius is 6, so we find the area of sector to be:</em>
Secondly, we find area of triangle (isosceles) =
where
a and b are the two sides bordering the known angle, so a=b=6, and
C is the angle which is <em>60°</em>
Now we find the area to be:
Hence, area of shaded =
Rounding to nearest whole number, area of shaded region = 3m^2
The value is 1, any number multiplied by 0 is 1
O A O
S H C H T A
Looking for s (sin)
O
So you use the triangle of S H
O = opposite
H = hypotenuse
So you’d then do the O/H
So the opposite being 12cm and the hypotenuse being 13cm
The answer would then be 13/12
Hope this helps! :)
Answer:
x = -6
Step-by-step explanation:
4x - 2 - 8x = 22
-4x - 2 = 22
-4x = 24
4x = -24
x = -6
Answer:
I know that a= 124 but I'm afraid I don't know how to solve b. I thought I'd put down half an answer anyway incase that helps.
Step-by-step explanation:
The exterior circle angles all have to add up to 360 degrees so all you have to do is subtract 100 and 136 from 360 and you get 124 for a.
