pinakimandal53: What is the sum of these angles? Or they are complementary or supplementary angles?

Answers

Answered by Durgeshraghuwanshi

let the angle be 2x and 7x then sum of it will be 90 degree as given in question .angles
=2x + 7x = 90
9x = 90
X=10
first angle =2 multiply X = 20
second angle =7×x =70

Let the angles be 2x and 7x.
∵ These angles are complementary.
∴ The sum of these angles is 90.

Now, I am going to solve and equation and find the value of x.
$2x+7x=90$
Add 2x and 7x.
$9x=90$
Divide both sides by 9.
$\frac{9x}{9} = \frac{90}{9}$
Simplify.
$x=10$

Now, we know that the value of x is 10. We are going to find the angles.
2x = 2×10 = 20
7x = 7×10 = 70

∴ The angles are 20° and 70°.

Hope this helps you.

Saanvipriya: how do you make small pics

pinakimandal53: Which pics?

Saanvipriya: small pics between the equations

Saanvipriya: like x=10

pinakimandal53: Those are not pics. There is an option for writing an equation and inserting it into an answer.

Saanvipriya: where

pinakimandal53: When you write an answer, you see 4 symbols. One of the options looks something like this 'π'. Click on that symbol and you will be able to write an equation. Then click on the Insert button.
