Question

DEF ~ GEH What is the missing value of q?

Answer 1

Explanation:

Line DF equals 20 and Line EF equals 15

Since the triangle is congruent we can set up the ratio:

15:20 equals 45:q

after setting this ratio as a fraction:

15/20 equals 45/q

we can cross multiple

20x45=900

900 dived by 15 =60

q=60

Answer 2

60

Explanation:

These are similar triangles so we can write the following equation to find the value of q:

`(q)/(20) = (45)/(15)`

• Cross multiply fractions.

15q = 900

• Divide both sides by 15.

q = 60
