Determine x,y, and z.
80°
100°
55°
60°
The measure ofx is
The measure of y is
The measure of z is
Answer:
Step-by-step explanation:
You can get y and x immediately. z is a bit tricky.
x
The other two angles of a triangle containing x are 100 and 60.
x + 100 + 60 = 180 Add the two terms on the left
x + 160 = 180 Subtract 160 from 180
x = 180 - 160 Combine the right
x = 20
y
y is done exactly the same way.
55 + 80 + y = 180
135 + y = 180
y = 180 - 135
y = 45
z
You have x y and z all in the same triangle. You know x and y so z can be found in much the same way.
x + y + z = 180
20 + 45 + z = 180
65 + z = 180
z = 180 - 65
z = 115
Answer: x = 20
y = 45
z = 115
Step-by-step explanation:
There is one unknown variable in both triangles with known angles. To find the values of x, y, and z, add both the known angles and subract it from 180 degrees. The result will be the value of the variable. When you have both the values of x and y, do the same math to find the value of z.
Step 1: Find the value of x
Add the values of the two known angles in this traingle and subtract it from 180°
80 + 55 = 135
180 - 135 = 45
45° is the value of x
Step 2: Find the value of y
Add the values of the two known angles in this traingle and subtract it from 180°
100 + 60 = 160
180 - 160 = 20
20° is the value of y
Step 3: Find the values of z
Add the values of x and y and subtract it from 180°
45 + 20 = 65
180 - 65 = 115
115° is the value of z
The sum of three numbers is 45. The second of the three numbers is three more than twice the first number, x. The
third number is two more than the first number, x. Which equation can be used to solve for the first number, X?
Ox+ 5x + x + 2 = 45
O x + x + 3 + x + 2 = 45
O x + 3x + 2 + x + 2 = 45
O x + 2x + 3+x+ 2 = 45
The option D is correct

Answer:
A
Step-by-step explanation:
You want to find out how much it would be for 15 boxes
(5 , 11.25)
this is the first pair on the table multiply both by 3 because 5 x 3 = 15(boxes)
so we need to find how much it costs so now you multiply 11.25 by 3 which will be 33.75.

PLA ANSWER I DONT KNOW THIS
Answer:
x=45
Step-by-step explanation:
I can give you two solutions
First solution:
In [tex]\triangle FBA[/tex] we know that
[tex]\angle BFA + \angle FAB + \angle ABF=180\\\\90+x+\angle ABF =180\\\\\angle ABF =90-x[/tex]
same case for [tex]\angle EBC[/tex] in [tex]\triangle ECB[/tex]
so we have that
[tex]\angle ABC = \angle ABF + \angle FBE +\angle EBC\\\\\angle ABC = 90-x+45+90-x\\\\\angle ABC = 180+45-2x[/tex]
we leave it like that because it's convenient
Now by properties of parallelograms we know that opposite sides add up to 180
[tex]\angle FAB + \angle ABC = 180\\\\x+180+45-2x=180\\\\x+45-2x=0\\\\45-x=0\\\\x=45[/tex]
so one angle is 45 and the other one is 135
Solution 2
if we look at DEBF we can say that it's a cyclic quadrilateral
because opposite sides add up to 180
in our case
[tex]\angle DFB = 180 -\angle BFA = 180-90 = 90\\\\\angle DEB = 90\\\\\Rightarrow \angle DFB + \angle DEB = 180\\\\[/tex]
so for the other to angles is also true
[tex]\angle FDE + \angle EBF = 180\\\\\angle FDE +45 = 180\\\\\angle FDE = 135[/tex]
so that's the measure of one angle of the parallelogram
the other angle x is
[tex]\angle EDF + \angle FAB = 180\\\\135+x=180\\\\x=45[/tex]

A piano teacher charges $20 per lesson plus a $30 fee for supplies. Another
teacher does not have a supply fee but charges $30 per lesson. After how
many lessons will the cost of the two teachers be the same?
Answer:
3 Lessons
Step-by-step explanation:
Find out the difference between the initial price of each lesson. In this equation it's $10. With that being said, for every lesson the difference will always be $10. So the next lesson would be a $20 lesson and so forth. By the third lesson the difference would be $30. You add the $30 to the $30 per lesson teacher and you'll get $90 which would be equal to the teacher doing it for $30 an hour to begin with.
The total number of lessons when the cost of the two teachers be the same is 3 and this can be determined by forming the linear equation.
Given :
A piano teacher charges $20 per lesson plus a $30 fee for supplies. Another teacher does not have a supply fee but charges $30 per lesson.The following steps can be used in order to determine the total number of lessons will the cost of the two teachers be the same:
Step 1 - Let the total number of lessons be 'x'.
Step 2 - The total amount of money the first piano teacher earn is:
= 20x + 30
Step 3 - The total amount of money another piano teacher earn is:
= 30x
Step 4 - According to the given data, the cost of the two teachers be the same, that is:
20x + 30 = 30x
Step 5 - Simplify the above equation.
30 = 10x
x = 3

A triangle has sides of length 2 cm, 8 cm and 9 cm.
Calculate the value of the largest angle in this triangle.
:)
Answer:
113.97 degrees
Step-by-step explanation:
use the cosine rule for finding an angle
cosA = b^2 + c^2 - a^2
2bc
In the given triangle angle A is greatest than any other angle.
What is the triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
Given sides of triangle, a=2cm,b=8cm,c=9cm
cosine law
Cos A = [tex]\frac{-a^2 + b^2 + c^2}{ 2bc}[/tex] = [tex]\frac{64 + 81 - 4 }{2 * 8 *9}[/tex] = 141/ 144
Cos B = [tex]\frac{a^2 - b^2 + c^2}{ 2ac}[/tex] = [tex]\frac{4 + 81 - 64}{2 * 2 *9}[/tex] = 21/36
Cos C = [tex]\frac{a^2 + b^2 - c^2}{ 2ab}[/tex] = [tex]\frac{4 + 64 -81}{2 * 2* 8}[/tex] = -13/52
A = Cos⁻¹ (141 /144 )
B = Cos⁻¹ (21/ 36 )
C = Cos⁻¹ (-13/52 )
Thus Angle A < Angle B < Angle C.
Therefore, Angle A is the greatest in the triangle.
