Answer:

a) Acute

Step-by-step explanation:

To clasify the triangle as Acute, Right, or Obtuse, we use the converse of the pythagorean theorem and see if c^2 is greater, less than, or equal to b^2+a^2.

So 16^2 ? 11^2 + 12^2

Since 11^2 +12^2 = 265 and 16^2 is 256, c^2 is less than b^2+a^2. So the triangle is acute.

Answer:

a) Acute

Step-by-step explanation:

If 11 and 12 were the legs of a right triangle, the length of the hypotenuse would be ...

√(11² +12²) = √(121 +144) = √265 ≈ 16.3

The actual length of the longest side is shorter, so the opposite (largest) angle measure will be <em>less than 90°</em>. The triangle is acute.

Answer:

115% of 75 is equivalent to 75 by 1.15 = 8.625 , This two are equivalent

Step-by-step explanation:

Given as :

Tyson multiplies 75 by 1.15

I .e 75 × 1.15 = 86.25

Now A ) 115% of 75 = $\frac{115}{100}$ × 75 = 86.25

B) 15% of 75 = $\frac{15}{100}$ × 75 = 11.25

C) 11.5% of 75 = $\frac{11.5}{100}$ × 75 = 8.625

D) 1.15% of 75 = $\frac{1.15}{100}$ × 75 = 0.8625

∵ 115% of 75 is equivalent to 75 by 1.15 , so Tyson try to find the option A
