Answer:
x = 79°
Step-by-step explanation:
The arrows on the line segments indicate that the lines are <u>parallel</u>.
As the parallel line segments are the <u>same length</u>, the other pair of opposite line segments are also parallel and the same length. Therefore, we can apply the Alternate Interior Angles Theorem.
<u>Alternate Interior Angles Theorem</u>
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
Therefore, the missing angle in the triangle including angle x is 28°.
Interior angles of a triangle sum to 180°
⇒ 73° + 28° + x = 180°
⇒ x = 180° - 73° - 28°
⇒ x = 79°
As there are 6 friends then each friend gets an equal amount so the popcorn is 48:6 or 8:1 the unit rate is 154:6 or 24:1 so the answers are 8:1 and 24
Answer:
15.5%
Step-by-step explanation:
No of students that had enrolled last year = 225
This year, 260 students are enrolled.
We need to find the percent of change in the number of students. It can be calculated as :
P = (change in no of students/initial no of students)×100
So, the percent change is 15.5%.
