(-5, 1) is the same because it is a dot
Answer:
Option (1)
Step-by-step explanation:
Lines X and Y are intersecting at a point.
Two pairs of vertical angles have been formed at the point of intersection.
1). ∠1 and ∠3
2). ∠2 and ∠4
It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]
If line Y is rotated 5° clockwise about the point of intersection of both the lines,
∠1 and ∠3 both will increase by 5°.
Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).
Option (1) will be the answer.
Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is

b - base
h - height
the first step is to add the information that we know into the formula.
We know the area =
and the height = 5 inches

if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area (
) we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A = 
A =
(30 ÷ 2 = 15)
A = 15
