Find the area. The figure is not drawn to scale
poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

(hypotenuse)^2=(base)^2+(perpendicular)^2

(AB)^2=(BC)^2+(AC)^2

(10)^2=(8)^2+(AC)^2

100=64+(AC)^2

100-64=(AC)^2

36=(AC)^2

take square root

6=AC

Then area of triangle ABC =\frac{1}{2}\left(base\right)\left(altitude\right)

=\frac{1}{2}\left(8\right)\left(6\right)=24

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.

(-11-10i)^2<br> I just need to know the steps to get to the answer.
jeka57 [31]

Answer:

21 + 220i

Step-by-step explanation:

reminder that i² = - 1

(- 11 - 10i)²

= (- 11 - 10i)(- 11 - 10i) ← expand using FOIL

= 121 + 110I + 110I + 100I²

= 121 + 220I + 100(- 1)

= 121 + 220i - 100

= 21 + 220i

What is the absolute value of the complex number Negative 4 minus StartRoot 2 EndRoot i?
IRINA_888 [86]

Answer:

3\sqrt{2}

Step-by-step explanation:

For the complex number a+bi, the absolute value is \sqrt{a^2+b^2}

Given the complex number -4-\sqrt{2}i. For this complex number,

a=-4\\ \\b=-\sqrt{2},

then the absolute value is

\sqrt{(-4)^2+(-\sqrt{2})^2}=\sqrt{16+2}=\sqrt{18}=3\sqrt{2}
