Fiona is making a scale model of a set for her school theatre. The stage in the theatre has a width of 42 feet. She is using the scale that 1 inch on her model is equal to 3.5 feet on the real stage. What will be the width, in inches, of Fiona's model?

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

i think it is c hope that

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
