How do i solve exterior angles on triangles (picture)

Answers

Answer 1

Answer: remember
the exterior angle=sum of the other 2 interior anlges

therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27

other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52
attachment below (in degrees)

Answer 2

Answer: you recieve exterior angles by adding the degrees

Find the areaRenata is completing a craft project that involves covering only the lateral surface of a cylindrical container with fabric. The cylinder has a height of 12.8 in. and a radius of 15.1 in. To the nearest square unit, how much fabric does she need for this project? Use a calculator.

Answers

Answer: Renata needs 1,214 square inches fabric for this project.

Data:
Height of the cylinder: h=12.8 in
Radius of the cylinder: r=15.1 in
Lateral surface of the cylinder: S=?

Solution:
S=2 Pi r h; Pi=3.1416

Replacing the known values:
S=2 (3.1416) (15.1 in) (12.8 in)
S=1,214.416896 in^2
S=1,214 in^2

Liam calculated the slope of line AC between points A and B. Olivia calculated the slope of line AC between points B and C. Both Liam and Olivia drew triangles, as shown below, to calculate the slopes: A graph shows numbers from 0 to 27 on the x axis at increments of 3 and the numbers 0 to 6 on the y axis at increments of 1. A line AC is drawn that joins the ordered pairs 0, 0 and 27, 6.The ordered pair 9, 2 is labeled as B. A right triangle is drawn with AB as hypotenuse and height 2 units. Another right triangle is drawn with BC as the hypotenuse and height 4 units.

Which statement is correct about the slopes calculated by Liam and Olivia if both calculated the slopes accurately?

Liam calculated the slope as 2 over 9 and Olivia calculated it as9 over 2.
Liam calculated the slope as 9 over 2 and Olivia calculated it as2 over 9.
Both calculated the slope as 2 over 9.
Both calculated the slope as 9 over 2.

Answers

Liam calculated the slope of line AC between points A(0,0) and B(9,2):
m=(9-0)/(2-0) = 9/2
Olivia calculated the slope of line AC between points B(9,2) and C(27,6):
m=(27-9)/(6-2)=18/4=9/2
Answer: Both calculated the slope 9 over 2.

The correct statement about the slopes they both calculated is: D. Both calculated the slope as 9 over 2.

How to Calculate Slope of a Line?

Slope = rise/run = change in y / change in x

Slope of line AC calculated by Olivia by Liam = (9-0)/(2-0)

= 9/2

Slope of line AC calculated by Olivia = (27-9)/(6-2)

= =18/4

= 9/2

The true statement about the slopes calculated would be: D. Both calculated the slope as 9 over 2.

Can someone simplify this expression? 14y – 5(3 – 2y) and explain how you got it.

Answers

you first expand the brackets so
14y-15-10y
then you put the like terms together so you do 14y-10y= 4y
4y-15 which is the answer

14y - 5(3-2y)
Distribute what's in the parenthesis
14y- (15+10y)
Combine like terms
24y-15
