Answer:
3) 16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
CB/CD = CF/CA
CB = CD·CF/CA = 7.2·21.6/9.6
CB = 16.2
_____
When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
Answer: 5/3, 2
It’s going up by 1/3 so just add 1/3 to 4/3 for the next term.
1/3 + 4/3 = 5/3
Now add 1/3 to 5/3 for the best term
5/3 + 1/3 = 6/3 = 2
Answer:
function
Step-by-step explanation:
A <u>function</u> is a rule that pairs each element in one set with exactly one element from a second set.
