Keith_Richards [23]

Answer:

B. $\dfrac{1}{2}ab$

Step-by-step explanation:

Given the proof below:

<u>Proof of Pythagorean theorem.</u>

Step 1: Given yellow triangle abc

Step 2: Construct 3 triangles congruent to yellow triangle abc.

Step 3: $(a + b)^2 = c^2 + 4(\dfrac{1}{2}ab)$

Step 4: $a^2 + 2ab + b^2 = c^2 + 2ab$

Step 5: $a^2 + b^2 = c^2$

Since Area of a Triangle = $\frac{1}{2}X$Base X Height$

The expression that represents the area of each triangle is <u>Option B.</u>

What is the approximate length of minor arc JH? Round to the nearest tenth of a centimeter.

vladimir1956 [14]

The length of the arc is 3.5 cm

<h3>How to determine the arc length?</h3>

The attached image completes the question

The given parameters are:

Diameter, d = 16
Central angle, x = 25

The length of the arc is calculated as:

$L = \frac{x}{360} * \pi d$

So, we have:

$L = \frac{25}{360} * 3.14 * 16$

Evaluate the product

L = 3.5cm

Hence, the length of the arc is 3.5 cm
