Alexus [3.1K]

Answer:

Step-by-step explanation:

The number of oranges with brothers be 6x, 4x , 2x

The brother with the largest share had 150 oranges. So,

6x = 150

x = 150/6

x = 25

4x = 4 * 25 = 100

2x = 2 *25 = 50

the number of oranges shared​ = 150+100 + 50 = 300 oranges

Find the value of x. Then find the angle measures of the polygon.
Minchanka [31]

Answer:

35° , 40° , 105°

Step-by-step explanation:

the sum of the 3 angles in the triangle = 180° , then

3x + x + 40 = 180 , that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

3x = 3 × 35 = 105

the 3 angle measures are 35° , 40° , 105°
