The correct reason for statement 5 is Commutative Property.
Answer:
14910 meters
Step-by-step explanation:
3 weeks= 21 days
each day= 710 m
21 days= 710*21
21 days= 14910 m
The basic deal is a^2 + b^2 = c^2
A= incorrect, 81 + 100 does not equal 121.
B= incorrect, 64 + 144 does not equal 256.
C= incorrect, 256 + 1024 does not equal 1280
This leaves D.
D must be a right triangle.
The answer is 5, 6, 7
Because
6456 < 6512 < 6788
6456 < 6612 < 6788
6456 < 6712 < 6788
It would be A, Side Angle Side (SAS). Because you are given we congruent sides, and tow right angles. Using the reasoning of "If two two angles are both right angles then they are congruent" you can prove the angles congruent.
The reason it is not HL is because HL is used when it is given a right angle and the hypotenuse and one of the legs congruent. Therefore the only choice is Side Angle Side (SAS).
