Answer:
14.5 degrees
Step-by-step explanation:
The total amount of degrees in a triangle is 180
67.5+55=122.5 degrees
That means that there would be 57.5 (180-122.5) degrees left for the measure of angle 3x+14.
3x+14=57.5
-14 -14
3x=43.5
x=14.5
Answer:
Since this is an equilateral triangle, the two angles at he bottom are equal. 55-14= 41, and 41/3= 13 2/3, so x=13.6 repeating.

Background Information
Squares and Square Roots
A square is a 2-dimensional (2-D) shape with all four sides equal.
The total area the square covers is measured in square units.
To determine the side length of a square when given the area, the square root must be
determined.
A perfect square can be described as
Q a square with whole number sides (e.g., 1 × 1, 2 × 2, 3 × 3)
Q a number whose square root is an integer (e.g., 4 = 2 or –2)
A non-perfect square can be described as
Q a square with non-whole number sides (e.g., 1.2 × 1.2)
Q a number whose square root is not a whole number (e.g., 2)
Rounding is often used to determine the approximate square root of non-perfect
squares.

-11 degrees is warmer than -15 degrees, -10 feet is closer than -8, the temperature is -2, the divers' elevation is 10 feet of elevation, and the whale goes 600 feet in all to breath, & to feed.

emily and andy each go to a hardware store to buy wire. The table shows the cost y in dollars for x inches of the wire they need. emily needs 21 feet of the wire. andy needs 13 yards of the wire. How much will each of them spend for wire?

The equation that represents the cost of the wire for a certain length will be y = (3 / 50)x.
What is a line passing through two points?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
Emily and andy each go to a home improvement shop to purchase wire. The table shows the expense y in dollars for x crawls of the wire they need.
Take two points from the table, then we have
(120, 7.2) and (125, 7.5)
Then the equation of the line is given as,
(y - 7.2) = [(7.5 - 7.2) / (125 - 120)](x - 120)
y - 7.2 = (3/50)(x - 120)
y - 7.2 = (3/50)x - 7.2
y = (3 / 50)x
The equation that represents the cost of the wire for a certain length will be y = (3 / 50)x.

Answers
Answer:
a. 18
Step-by-step explanation:
First you multiply 24 by 9 since each bow is 9 inches and she needs 24 bows.
After multiplying you should then end up with 216 in. Then convert 216 into feet which should give you 18.
