I cant really explain sorry
<span> 30-60-90
The hypotenuse is equal to twice the length of the shorter leg, which is the side across from the </span>30<span> degree angle.
answer
A) first one
5, 5sqrt3 legs and hypo 10</span>
Formatting first:
Step 1: (6.2 − 1.6) − 4.4 + 7.8
Step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)
Step 3: 6.2 − 6 + 7.8
Step 4: −14 − 6 = 8 (commutative property)
Step 5: 14 − 6 = 8
Step 2 is the associative property (a+b)+c=a+(b+c)
Step 4 is just wrong with -14 instead of 14; seems corrected in step 5.
Answer: He wrote commutative instead of associative in Step 2.
