Answer:

75π in²

Step-by-step explanation:

The shaded sector is 3/4 of the circle. We can use the area formula for a circle to find the area of the whole circle, then multiply that result by 3/4.

A = πr² = π(10 in)² = 100π in²

Then the area of 3/4 of the circle is ...

3/4·A = (3/4)·100π in² = 75π in²

A triangle has side lengths of 39, 80, and<br> 87. Is this triangle a right triangle?

iren2701 [21]

Answer:

Step-by-step explanation:

39²=1521

80²=6400

39²+80²=1521+6400=7921

87²=7569

7921≠7569

so it is not aright angled triangle.

Answer:

(3/4) -(1/4)i

Step-by-step explanation:

Your answer is correct.

$\dfrac{5}{6+2i}=\dfrac{5(3-i)}{2(3+i)(3-i)}=\dfrac{5(3-i)}{2(9+1)}\\\\=\dfrac{3-i}{4}=\dfrac{3}{4}-\dfrac{1}{4}i$
