Answer:
45 because an acute angle is 45 degrees
Data:
l and m are parallel lines
QR and ST are perpendicular in R
Angle 1 is 63°
The angle formed by perpendicular lines is a right angle (90°)
Angles 1 and 3 are alternate angles: angles that occur on opposite sides of a transversal line that is crossing two parallel.
Alternate angles are congruent, have the same measure.

The sum of the interior angles of a triangle is always 180°. In triangle QRT:

Use the equation above to find the measure of angle 2:

Then, the measure of angle 2 is 27°
13 is not a perfect square so it is (irrational)
Answer:
Step-by-step explanation:
18/60-12/60= 4 miles
just my guess
Answer:
The length is 14 units
Step-by-step explanation:
Take the value at point F and subtract the value at point E
F = 19
E = 5
19 -5 =14
The length is 14 units
