Answer:
a = 3
Step-by-step explanation:
Calculate the distance d using the distance formula and equate to 4
d =
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)
d = =
=
= a + 1 then
a + 1 = 4 ( subtract 1 from both sides )
a = 3

Answer:
Let the number be x.
Given the statement: The ratio of the measure of the three angles is, 4 : 5 : 6.
Then, the angles be 4x , 5x and 6x respectively.
We know that: The sum of all the measures of angles is 180 degree.
then;
Combine like terms;
Divide by 15 both sides we get;
Then, the measure of each angle of triangle:
