Please help w/ geometry!

lara [203]

Answer:

<XYZ = 34

Step-by-step explanation:

Remark

Bisected angles means that the original angle (<XYZ in this case) has been cut exactly in half. The two parts that were created from <XYZ are equal so you need only solve for x, solve one of the halves and then double it.

Equation

3x - 7 = 2x + 1

Solution

3x - 7 = 2x + 1 Add 7 to both sides

3x - 7+7 = 2x +1+7 Combine

3x = 2x + 8 Subtract 2x

3x-2x = 2x-2x + 8 Collect like terms on both sides

x = 8

Solution 2

Find one of the bisected parts. You can choose either of the two parts so use 2x + 1

2x + 1

2*8+1

16 + 1

17

WYZ = 17 degrees

Solution 3

Double <WYZ to get <XYZ

<XYZ = 2 * 17

<XYZ = 34 degrees

I need help with 25 i dont know how to put it on a double line bar

Kipish [7]

Use proportion
25%/100 division sign 10/x
100 * 10=25x
1000=25x
x=1000/25
x=40
so 40 is your answer
you welcome

3. Two cars are parked, 150m apart, and on opposite sides of a building. A camera on the top of the building rotates and can vie

allsm [11]

Answer:

<em>The building is 61.5 m tall</em>

Step-by-step explanation:

The image below is a diagram where all the given distances and angles are shown. We have additionally added some variables:

h = height of the building

a, b = internal angles of each triangle

x = base of each triangle

The angles a and b can be easily found by subtracting the given angles from 90° since they are complementary angles, thus:

a = 90° - 37° = 53°

b = 90° - 42° = 48°

Now we apply the tangent ratio on both triangles separately:

$\displaystyle \tan a=\frac{\text{opposite leg}}{\text{adjacent leg}}$

$\displaystyle \tan 53^\circ=\frac{150-x}{h}$

$\displaystyle \tan 48^\circ=\frac{x}{h}$

From the last equation:

$x=h.\tan 48^\circ$

Substituting into the first equation:

$\displaystyle \tan 53^\circ=\frac{150-h.\tan 48^\circ}{h}$

Operating on the right side:

$\displaystyle \tan 53^\circ=\frac{150}{h}-\tan 48^\circ$

Rearranging:

$\displaystyle \tan 53^\circ+\tan 48^\circ=\frac{150}{h}$

Solving for h:

$\displaystyle h=\frac{150}{\tan 53^\circ+\tan 48^\circ}$

Calculating:

h = 61.5 m

The building is 61.5 m tall
