How to find the decimal form of 9/5 without dividing

1.8

Step-by-step explanation:

We are given that a number

We have to find the decimal form of given number without dividing

Given number

Multiply both  denominator and numerator with 2

Then, we get

When 10 in the denominator then we write decimal point after one digit when we go one step from right to left .

Then, the number can be written as in decimal form=1.8

x = -5

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
