1] 0.23
2] both are same
3] 20/100 *80= 16
Answer:
m<1 = 87
m<2 = 45
m<3 = 45
m<4 = 52
Step-by-step explanation:
if BC intersects <ACD then that means angle 2 and 3 = 90
so that being angle 2 and 3 are the same
now you do 180-(45+48) = 87
now same thing but 180-(45+83) = 52
Slope
m = (y2-y1)/(x2-x1)
m = (10 - 7)/(2 --1)
m = 3/3
m = 1
To find the equation
y = mx + b
m is slope
y = 1x + b
plug in one of the equations to solve for b
10 = 1(2) + b
10 = 2 + b
subtract 2 from both sides
8 = b
The equation is
y = 1x + 8
or you can write it as
y = x + 8
Hope this helps
Answer: 45°
Step-by-step explanation:
Diameter= 16m
Radius= 16/2 = 8m
The area of the circle= πr^2
= π8^2
= 64π square metres.
An area of 8π square metres is also 1/8 of the total area, therefore the arc must be 1/8 of the circumference.
The circumference = 2πr = 16π,
This gives us an arc length of 2π metres.
But since we are looking for the the angle.
In degrees: 360/8 = 45°
