Help solve for X, please hurry I have 42 minutes

Answers

Answer 1

Answer:

A) 9

Step-by-step explanation:

First you need to find the measure of angle c

Since it's a quadrilateral, the interior angles add up to 360 degrees

Now there's two right angles and one 99 degree angle

Add those and subtract from 360

360 - (90+90+99) = 81

C = 81 degrees

However x is the root of c so root 81 is 9

What is the area of the following right triangle?

Answers

Answer:

30 square units

Step-by-step explanation:

The area of the given right triangle can be found a couple of ways:

Pythagorean theorem

The missing side length can be found using the Pythagorean theorem relation between the sides:

c² = a² +b²

13² = a² +5²

a² = 169 -25 = 144

a = √144 = 12

Then the area is ...

A = 1/2ab = 1/2(12)(5) = 30 . . . square units

Trigonometry

The angle at lower right can be found from the trig relation ...

Cos = Adjacent/Hypotenuse

cos(A) = 5/13

A = arccos(5/13) ≈ 67.38°

The area can be found from these side lengths and the angle:

A = 1/2bc·sin(A)

A = 1/2(5)(13)sin(67.38°) = 30 . . . square units

_____

Additional comment

The sine of the angle can be computed from the cosine using the identity ...

sin(x) = √(1 -cos²(x))

In this case, the sine of the angle would be found to be 12/13, so the area would be computed as ...

A = 1/2(5)(13)(12/13) = 1/2(12)(5) . . . . same as using the Pythagorean theorem

Answer: A
Explanation: using the common ratio we can solve this. 24:8 = x:4
24 divided by 8 is 3.
Therefore x divided by 4 should be 3 too.
4 multiplied by 3 is 12, so x = 12.
For y:
When triangles are similar, the angles are always the same. So y is simply 40 degrees.
