How do you get the answer help please​

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.

the equation is going to be

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
