Answer:
33 feet.
Step-by-step explanation:
If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion
5.5/3 = x/18 and cross multiply to find x.
5.5 × 18 = 99
3 × x = 3x
3x/3 = x, 99/3 = 33.
x = 33.
it would take Janis 14 minutes to complete a package alone
<h3>How to determine the value</h3>
From the information given,
Let's say that
Carol working time = x = 30 minutes
Janis working time = y
x + y = 16 minutes
Let's make 'y' the subject
30 - 16 = y
y= 14 minutes
Thus, it would take Janis 14 minutes to complete a package alone

It is 16 minus 42b. (16 - 42b)
Answer:
Step-by-step explanation:
Supplementary angles are two or more angles whose the addition of their measures add up to 
.
Given: <1 and <2.
<1 + <2 = (supplementary angles)
If <1 ≅ <2 (congruent property), then we have;
<1 + <1 =
2<1 =
<1 = 
= 
<1 =
So that since <1 and <2 are congruent, then;
<1 ≅ <2 ≅
Therefore if <1 and <2 are supplementary and congruent, then they are right angles.
