Emma wants to enlarge a square photo and print it to a canvas. The side length of the canvas is 12in. The scale from the canvas to the photo is 4in. to 1 in. What is the side length of Emma’s Photo?

The side length of Emma's photo = 3 inches

Step-by-step explanation:

Emma wants to enlarge a square photo and print it to a canvas.

From the above question, we can deduce that:

The scale

= The side length on the canvas : The side length of the photo

= 4in : 1 in.

What is the side length of Emma’s Photo?

The side length of the canvas is 12in.

Hence:

Side length on the canvas/ Side length of the photos

4 in/1 in = 12 in/x in

Cross Multiply

= 4 × x = 1 × 12

= x = 12/4

x = 3 inches

Hence, the side length of Emma's photo = 3 inches

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
