61+58=119
180-119=61=angle 2
180-61=119=angle 4
It’d be 2
250 ÷20= 12.5
25 ÷2=12.5
If you were to solve for y, it would be 2. Therefore 2y would be 4.
Every <em>1 millimeter</em> on the actual object is only <em>2 centimeters </em>on the scale drawing.
(If you don't know which is which, think of the colon as "represents")
2 cm (=20 mm) is far larger than 1 mm, so the scale drawing must be larger.
