Amiraneli [1.4K]

Answer:

8.4 inches

Step-by-step explanation:

To find the amount of inches, multiply the length by the percent. A percent is 40% but can also be written as a decimal conversion as 0.4. Then 40% of 60 inches is 0.4(60)= 24 inches.

However, she didn't use all 24 inches. She used 35%. This converts to 0.35 and then multiply for 0.35(24) = 8.4 inches.

She used 8.4 inches.

Answer:

It is the right-angled triangle.

Step-by-step explanation:

According to the Pythagorean theorem, a^{2}+b^{2}=c^{2}, which c is the longest side of the triangle.

So, 27^{2}+36^{2}=45^{2} if the triangle is right angle.

LHS=27^{2} + 36^{2} = 2025

RHS=45^{2}=RHS=45^{2} = 2025

∵LHS=RHS

∴It is a right-angled triangle.
