About
Simple and Easy Learning
Tutorials Point originated from the idea that there exists a class of readers who respond better to online content and prefer to learn new skills at their own pace from the comforts of their drawing rooms.
The journey commenced with a single tutorial on HTML in 2006 and elated by the response it generated, we worked our way to adding fresh tutorials to our repository which now proudly flaunts a wealth of tutorials and allied articles on topics ranging from programming languages to web designing to academics and much more.
40 million readers read 100 million pages every month
Our Text Library Content and resources are freely available and we prefer to keep it that way to encourage our readers acquire as many skills as they would like to. We don't force our readers to sign up with us or submit their details either to use our Free Text Tutorials Library. No preconditions and no impediments, Just Simply Easy Learning!
We have established a Digital Content Marketplace to sell Video Courses and eBooks at a very nominal cost. You will have to register with us to avail these premium services.

To do:We have to find the angle which is equal to its complement.Solution:Two angles are said to be complementary if the sum of their measures is $90^o$.Let the required angle be $x^{\circ}$This implies, Its complement$=(90-x)^{\circ}$Therefore, $(90-x)^{\circ}=x^{\circ}$$(x+x)^{\circ}=90^{\circ}$$2x^{\circ}=90^{\circ}$Therefore, $x=\frac{90^{\circ}}{2}$$x=45^{\circ}$Hence, the angle which is equal to its complement is $45^{\circ}$.Read More

To do:We have to find the angle which is equal to its supplement.Solution:Two angles are said to be supplementary if the sum of their measures is $180^o$.Let the required angle be $x^{\circ}$This implies, Its supplement$=(180-x)^{\circ}$Therefore, $x^{\circ}=(180-x)^{\circ}$$(x+x)^{\circ}=180^{\circ}$$2x^{\circ}=180^{\circ}$$x^{\circ}=\frac{180^{\circ}}{2}$$x^{\circ}=90^{\circ}$Hence, the angle which is equal to its supplement is $90^{\circ}$.Read More

Given:The product of the two numbers is 80.One of the numbers is 4 times the other.To do:We have to find both numbers.Solution:Let one number be $x$.This implies, The other number $=4\times x$$=4x$The product of the two numbers is 80.This implies, $x \times 4x=80$$4x^2=80$$x^2=\frac{80}{4}$$x^2=20$$x=\sqrt{20}$$x=\sqrt{4\times5}$$x=2\sqrt5$$4x=4(2\sqrt5)=8\sqrt5$Therefore, the required numbers are $2\sqrt5$ and $8\sqrt5$.
