The diagram shows that
AB = 5
AC = AB+BC = 5+2 = 7
DE = 7
DF = DE+EF = 7+x
So,
AB/AC = DE/DF
5/7 = 7/(7+x)
5(7+x) = 7*7
5(7+x) = 49
35+5x = 49
5x = 49-35
5x = 14
x = 14/5
So EF = 14/5 in fraction form
In decimal form, EF = 2.8 (since 14/5 = 2.8)
We have the following:
The largest angle is always the angle opposite the longest side, therefore
The largest angle is
The answer to the question
Answer:
Option A
Step-by-step explanation:
Expression: y = 12h
If h = 15, then:
y = 12(15)
y = $180
Option A
