Answer:
a= 75°
β= 30°
Step-by-step explanation:
α = 75° This is because triangle PQR isosceles. Thus two of its angles are equal and these two are angle α and the one labelled 75.
β = 30° This is because angles in a triangle sum up to 180°. We already know two of these angles. To find β you say 180 - ( 75 × 2)
The answer becomes 30°.

it's 13 if you use the distance formula
Answer:
2(5x - 1) – (2x - 5)
=2(5x−1)−2x+5
=10x−2−2x+5
=(10x−2x)+(−2+5)
=8x+3

The perimeter of the rectangle will be given by the equation 2(x₂-x₁)+2(y₂-y₁).
<h3>What is the perimeter?</h3>
The perimeter is defined as the sum of all the sides of the figure. Here in the question, we have the rectangle with coordinates (x₁,y₁),(x₂,y₂),(x₂,y₁)(x₂,y₂).
So by using the distance formula we will find the length and width of the rectangle.
l=x₂-x₁
Width of the rectangle is given by
w=(y₂-y₁)
Hence, the perimeter of the rectangle is given by
P=2l+2w
P=2(x₂-x₁)+2(y₂-y₁)
