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

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.

Step-by-step explanation:
Your ratios total 3+3+4 = 10 units, so each unit must stand for 180°/10 = 18°.
Then the angles are found by multiplying the ratio values by 18°.
3 : 3 : 4 = 54° : 54° : 72°
