The difference between two numbers is 275.the smaller number is 236 what is the sum of the both numbers

let x (bigger) and y (smaller) be the number

difference, x-y = 275

y = 236

x = ?

~ x - 236 = 275

x = 275 + 236

x = 511

sum, x+y

y = 236

x = 511

511 + 236 = 747

hence, sum of the both number is 747.

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°.
