Answer:

Step-by-step explanation:

OA=OB=OC

∠A = ∠1

∠B = ∠2

∠A + ∠B + ∠C = 180°

∠A + ∠B + (∠1 + ∠2) = 180°

∠1 + ∠2 + (∠1 + ∠2) = 180° ... subtitution

2 x (∠1 + ∠2) = 180°

∠1 + ∠2 = 90°

∠ACB = 90°

Help guys I realy need help I will report you if you give me the wrong answer

Answer:

the Answer is 150x + 12100 ≤ 26500

Step-by-step explanation:

The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)

There is already 12100 killograms on the sipping containter so that is why you have + 12100

and you have 150x because x is the number of 150-kilogram crates

and for as many crates you have to multiply by the weight.
