Answer:
Transitive property of congruence.
Step-by-step explanation:
The transitive property of congruence states that if ∠A≅∠B, ∠B≅∠C then ∠A≅∠C.
For example:
x+5= 10 and 10= 5+5 then x+5= 5+5.
Answer:
600
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m. Since the tires revolve 15 times per second, this means every second the tires travel 15 m. This means that in 40 seconds, the tires travel15(40) = 600 m.
15 x 40 = 600
Answer:
9. Triangle ABQ is congruent to Triangle BAP because of SAS congruency
10. x=5, y isn't shown anywhere
Step-by-step explanation:
9. The side AB is shared between the two triangles.
It is given that angle A and angle B are congruent.
It is given that AQ is congruent with BP.
Using these three, you can say that Triangle ABQ is congruent to Triangle BAP because of SAS congruency.
10. 7x-4=31 (given)
x=5
Do the same thing with y.
