Answer:

1. 60

2. 120

3.30

Step-by-step explanation:

(Yes I know they aren't labeled one and two but I'll go in order from the questions)

1. It is 60, because it is an equilateral triangle so all angles are equal. 180/3=60.

2. There are two ways you can solve this problem. The first is using the vertical angle theorem. That makes it 120. Or, you can add all the angles you have already and remove it from 360.

360-120-60-60=120.

(you can tell it is not 60 because it is larger than a right angle in the picture)

3.x=30.The right angle is 90, and there is a 60 degree angle, so 90-60=30

Answer:

60

Step-by-step explanation:

Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)

a 28 inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third pi
klasskru [66]
Where x is the length of the first piece
x + 2x + 6x + 1 = 28 \\  \\ 9x = 27 \\  \\ x = 3
so the first piece is 3 inches, the second is 6 inches and the third is 19 inches

Where is the solution located on a graph a system of equations?
geniusboy [140]
For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.

4x²-y²=171 and 2x-y=9, value of 2x+y
11111nata11111 [884]
So you will need to solve for x and y before evaluating 2x+y....

2x-y=9, y=2x-9  now this will make 4x^2-y^2=171 become:

4x^2-(2x-9)^2=171

4x^2-(4x^2-36x+81)=171

36x-81=171

36x=252

x=7, now we can use 2x-y=9 to solve for y...

2(7)-y=9

14-y=9

-y=-5

y=5

now we know that x=7 and y=5, 2x+y becomes:

2(7)+5

14+5
