If these two shapes are similar, what is the measure of the missing length d?
(Bigger triangle length: d, 84m)
(Smaller triangle length: 30, 40m)
Since the two triangles are similar, their corresponding sides are proportional.
Using the formula for proportional triangles:
d / 30 = 84 / 40
Cross multiply to solve for d:
40d = 30 * 84
40d = 2520
d = 2520 / 40
d = 63
Therefore, the missing length d is 63m.
