Answer:
2.5
Step-by-step explanation:
The radius is half of the diameter. 5 / 2 = 2.5
Answer:
3 and - 4
Step-by-step explanation:
Calculate the gradients using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
Line A
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
= 3
Line B
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m =
=
= - 4
Y + 1 = 5(x - 7)
y + 1 = 5x - 35
y = 5x - 36
Answer:
angle y is 64⁰
Step-by-step explanation:
There are 2 ways to solve this.
first,
they are alternate angles
second,
you can solve by
180-64=116 (on a straight line)
180-116=64⁰
I'm not really good at explaining but hope this helps :)
Answer:
x=12
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2= 144
b=12 Therefore,
x=12
