CAN EXPLAIN FURTHER
The triangles are not similar
Answer:
They can both do 35 push-ups per minute, with an equal ratio between them.
Step-by-step explanation:
Given that Nora can do 70 push-ups in 2 minutes, and Luke can do 105 push-ups in 3 minutes, to determine if these rates from a proportion the following calculation should be performed:
70/2 = X
35 = X
105/3 = X
35 = X
Therefore, they can both do 35 push-ups per minute, with an equal ratio between them.
Answer: x = 65°
In order to solve this problem you need to know:
1. The sum of the interior angles of a triangle adds up to 180°.
2. Supplementary angles add up to 180°.
3. The sum of the interior angles of a hexagon adds up to 720°.
4. Vertical angles are congruent and have the same measure.
5. The exterior angle of a triangle is the sum of the nonadjacent interior angles.
