Solve 2*90^circ+(11-2)*120^circ=(277-4)*90^circ

$$2 \times 90 ^ { \circ } + ( 11 - 2 ) \times 120 ^ { \circ } = ( 277 - 4 ) \times 90 ^ { \circ }$$

Verify

Solution Steps

Multiply 2 and 90 to get 180.

$$180+\left(11-2\right)\times 120=\left(277-4\right)\times 90$$

Subtract 2 from 11 to get 9.

$$180+9\times 120=\left(277-4\right)\times 90$$

Multiply 9 and 120 to get 1080.

$$180+1080=\left(277-4\right)\times 90$$

Add 180 and 1080 to get 1260.

$$1260=\left(277-4\right)\times 90$$

Subtract 4 from 277 to get 273.

$$1260=273\times 90$$

Multiply 273 and 90 to get 24570.

$$1260=24570$$

Compare 1260 and 24570.

$$\text{false}$$
