Answer:

See answers below

Step-by-step explanation:

Since both trinagles asre similar hence the ratio of the similar sides are equal.

From both triangles;

y + 7 = 3y - 7

y - 3y = -7-7

-2y = -14

y = 14/2

y = 7

FE = 3y - 17

FE = 3(7) - 17

FE = 21 - 17

FE = 4

AB = y'+7

AB = 7 + 7

AB = 14

Similarly

3x+20 = 5x - 80

3x -5x = -80-20

-2x = -100

x = 100/2

x = 50

<A = 3x + 20

<A = 3(50) + 20

<A = 150 + 20

<A = 170degrees

Hence x= 50 and y = 7

A central angle is an angle made by 2 radii. Seeing as they want the measure of the angle that represents industry pollution, that would be 40% of the total 360 degrees.
40% = 0.4
0.4 × 360 = 144
The measure is 144 degrees.

11 less than 3 times a number is the same as 75 less than the product of minus 1 and the number what is the value of the number
DaniilM [7]

Answer:

(-16)

Step-by-step explanation:

Let the number  = x

11 less than 3 times a number: 3x -11

75 less than the product of minus 1 and the number: (-1)*x - 75 = -x -75

3x - 11 = -x -75

3x -11 +x = -75

4x - 11 = -75

4x = -75 +11

4x = -64

x = -64/4

x = -16
