1: B
because a triangle angles all have to add up to 180
Answer:
line s
Step-by-step explanation:
Using proportions, it is found that the thickness of the icing between the layers, in inches, is of:
E 1 inch
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, there are six layers, each measuring 1.25 inches tall, hence the height of these layers is:
6 x 1.25 = 7.5 inches
Then the height of the icing between the layers is of:
13.5 - 7.5 = 6 inches
Six layers, hence each icing is of:
6/6 = 1 inch

Y = mx + b
m = (y₂ - y₁)/(x₂ - x₁)
m= (6-3)/(20-5) and m = 3/15 = 1/5. Now calculate b.
To that end plug any of the 2 pairs value, let's take (5,3)
y = (1/5).x + b
3 = (1/5).(5) + b & b= 2
The equation: (1/5)x + 2
The y-value of the vertex is 1
