Answer:

We are given to find the length of side AB. We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units.

Find the missing the side of the triangle A. 130−−−√ m B. 179−−−√ m C. 42–√ m D. 211−−−√ m

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use the Pythagoras theorem to find the missing side

Using the Pythagoras theorem

That's

${a}^{2} = {b}^{2} + {c}^{2}$

From the question

x is the hypotenuse or the longest side of the triangle

Substituting the values into the above formula we have

${x}^{2} = {9}^{2} + {7}^{2}$

${x}^{2} = 81 + 49$

${x}^{2} = 130$

Find the square root of both sides

We have the final answer as

Hope this helps you

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)

klemol [59]

Answer:

52 $\pi$

Step-by-step explanation:

The total shaded are will be the area of big circle - not shaded circle + little shaded circle.

The are of big shaded circle: $\pi$ $r^{2}$ So, A= $\pi$ (8^2)= 64 $\pi$

The are of not shaded circle: $\pi r^{2}$ So, A= $\pi$ (4^2)= 16 $\pi$

The are of little shaded cirlce: $\pi r^{2}$ So, A= $\pi$ (2^2)= 4 $\pi$

64 $\pi$ - 16 $\pi$ + 4 $\pi$ = 52 $\pi$
