What is Trigonometry?One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.
As per the given data:
x = 41 cm
v = 17 cm
∠W = 134°
To find the length of w:
From the cosine law: [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]
[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]
Hence, the length of w is 54 cm.

What’s the measurement of
Step-by-step explanation:
4x and 6x sit on a straight line therefore must equal to 180°
4x+6x = 180° (∠'s on str. line)
10x = 180
x= 180/10
x= 18
Then we need to find ∠UYV
∠UYV = 4x
=4(18)
=72°
So ∠UYV = 72°

Jaime runs 2 and 1/4 miles in 1/4 of an hour how how many miles per hour does Jamie run
Answer:
9 miles
Step-by-step explanation:
1/4 of an hour is 15 minutes. So 2 and 1/4 times multiplied by 4 would be the answer beacsue 15 minutes times 4 is an hour.
Answer:
9 mph.
Step-by-step explanation:
We multiply the distance by 4 because there are 4 lots of a 1/4 in one hour:
That is 2 1/4 * 4
= (9/4) * 4
= 36/4
= 9 m ph.

Write 33 kg as a fraction of 4 tonnes.
Answer:
jsjjrjjsndndjjdjdjfjfjdjdjeoowke
The fraction of 33 kg as a fraction of 4 tonnes is 33/4000.
What is Unit Conversion?The same property is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other length unit instead of miles.
For example, inches, centimeters, and miles are all measures of distance.
Given:
Amount= 33 Kg
We have to convert Kg into Tones
We know, 1 tonne= 1000 Kg
So,4 tonee = 4 x 1000
= 4000 Kg
Thus, 33 kg as a fraction of 4 tonnes.
= 33/4000

How do you know when you have a difference of perfect squares?
In general, a variable to any even power is a perfect square.
So for example, x² is a perfect square and so is y¹⁴.
A common made by students is not in factoring the difference of two squares, but just failing to recognise that the difference of two squares exist.
It will also help to review your perfect squares
for the numbers between 1 and 16.
