Answer:
c
Step-by-step explanation:
a. 3in, 4in, 5 in
5^2 ? 3^2 + 4^
25 ? 9 + 16
25 = 25
Because the two sides are equal, this is a right triangle.
b. 5in, 6in, 7in
7^2 ? 5^2 + 6^2
49 ? 25 + 36
49 < 61
Because 49 < 61, this is an acute triangle.
c. 8in, 9in, 12in
12^2 ? 8^2 + 9^2
144 ? 64 + 81
144 < 145
Because 144< 145, this is an acute triangle.
Answer:
$80
Step-by-step explanation:
Area of Mr Jones's yard = 40 * 65 square feet
= 2600 square feet
Mr. Jones was charged $52 for the yard.
Therefore cost per square feet = 52/2600 = $0.02 per square feet
Area of neighbor's yard = 50 * 80 = 4000 square feet
Hence the neighbor will be charged 0.02 * 4000 = $80
For the area corresponding to the yard of size 4000 square feet, he will have to pay $80 to the landscaping company.
