Answer:
just sub and i think you get 108
Step-by-step explanation:
Dividing 40 into fifths...
40 ÷ 5 = 8
Since 1/5 of 40 is 8, 2/5 of 40 is <u>16</u>.
If you move the decimal point the same number of places in the dividend and the divisor, you are multiplying them both by the same power of 10. That does not change the quotient.
Since the triangles are similar the ratios of the lengths of corresponding sides are equal.
tan Q = opp/adj = RS/QS = YZ/XZ = 9/12 = 3/4
