Answer:
1. not equal, 2. equal, 3. 18
Step-by-step explanation:
7/5 =1.4
15/10=1.5
1.4 does not equal 1.5
6/8=.75
15/20=.75
.75 equals .75
1.2*3/2=1.8
Pythagorean Theorem: a^2+b^2=c^2
Plug in values.
15^2+sqrt(207)^2=(12sqrt(3))^2
225+207=432
432=432
Yes, this is a right triangle.
Answer:
$82.27
Step-by-step explanation:
