Find the lower bound of 40cm (WILL MARK YOU AS BRAINLIEST)

I can't tell you the answer, sorry but, I can tell you something

To find the lower bound of , subtract the upper bound of x – y from the lower bound of x. , If each of the numbers is given to two significant figures. The lower bound of the calculation is obtained by subtracting the upper bound of 4.5 from the lower bound of 7.3. Therefore lower bound of (7.3 – 4.5) is 2.7.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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°.
