100% represents the current size. To work out the new size, you add the percentage increase - this gives 107.5%

"per cent" means "per hundred" and is a ratio.

To work out the new value for p you multiply it by 107%.

To find a percentage, you multiply the the "percent" ratio and then divide by 100.

So 100% of p is: p * 100 / 100  (you can see here that 100/100 = 1, so the value is unchanged).

107% of p will be: p * 107 / 100

7. Isosceles triangle ABC is shown below with legs that measure 8 inches and a vertex angle of 50D. (a) Determine the area of AB
Flura [38]

Answer:

<h2>The area of the triangle ABC is 32 square inches.</h2>

Step-by-step explanation:

We know that the given triangle is a right-isosceles triangle, which means its leg are equal.

The area of a triangle is defined as

A=\frac{1}{2}bh

Where b=8 and h=8. Replacing values, we have

A=\frac{1}{2} \times 8 \times 8 = 32 \ in^{2}

Therefore, the area of the triangle ABC is 32 square inches.
