First, you need to know what a complementary angles are.
They are two angles that add up to 90 degrees.
If the number multiplied by 2 is 90, just to 90/2.
This gives you 45

Answer:

Area =62.5\sqrt{6} square units

AB=5\sqrt{15} units

BC=5\sqrt{10} units

Step-by-step explanation:

In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.

So,

BD^2=15\cdot 10\\ \\BD^2=150\\ \\BD=\sqrt{150}=5\sqrt{6}\ units

a. The area of the triangle ABC is

A_{ABC}=\dfrac{1}{2}\cdot BD\cdot AC=\dfrac{1}{2}\cdot 5\sqrt{6}\cdot (15+10)=\dfrac{125\sqrt{6}}{2}=62.5\sqrt{6}\ un^2.

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

AB^2=AD\cdot AC=15\cdot 25\Rightarrow AB=5\sqrt{15}\ units\\ \\BC^2=CD\cdot AC=10\cdot 25\Rightarrow BC=5\sqrt{10}\ units

Would you rather discover alien life or an animal that was thought to be extinct?
Vikentia [17]

\boxed{I\; would\; say\; an\; animal\; that\; was\; thought\; to\; be\; extinct.}

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.

What is the slope intercept form of the line that passes through the point (-2,-18) and has a slope of 1/4
mart [117]

Answer:

y=(1/4)x - 35/2

Step-by-step explanation:

y=mx+b

y=(x/4)+b                 plug in the slope (m)

-18=(-2/4)+b             plug in x and y

b= -17 1/2= -35/2     solve for b

y=(1/4)x - 35/2         plug in m and b into the equation
