Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
Answer:
-5
Step-by-step explanation:
y- 1/5x = 7
y= 1/5x +7
So, the slope of the line is 1/5
Perpendicular slopes are always the reciprocal with an inverse sign.
So, -5
Answer:
show a picture please i can still help you :3
Step-by-step explanation:
Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:
You should actually show congruency first
Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
