Solve for x and then determine the measure of the exterior angle.
neonofarm [45]

Answer:

x=25, 120

Step-by-step explanation:

The two angles form a straight line so they add to 180

60 + 4x +20 =180

Combine like terms

4x+80 = 180

Subtract 80 from each side

4x+80-80 =180-80

4x= 100

Divide by 4

4x/4 =100/4

x= 25

The exterior angle is

4x+20 = 4*25+20 =100+20 =120

a wheel has a diameter of 15cm. The wheel travels 50 metres. How many revolutions does the wheel complete?
TEA [102]

Answer:

106

Step-by-step explanation:

The diameter of the wheel is 15 cm or 0.15 m.

The circumference of the wheel is 0.15π m ≈ 0.47 m.

So the wheel moves 0.47 m with each revolution.

The wheel travels 50 m, so the number of revolutions is:

(50 m) / (0.47 m/rev) ≈ 106 revolutions.

5^3+5-6(4)<br><br> HELP FAST I’M IN CLASS
vodomira [7]

To solve: 5^3+5-6(4)

5^3+5-6(4) < first step, 5 to the third power is 125

125 + 5 - 6(4) < next step, 6(4) or 6 x 4 is 24

125 + 5 - 24 < third step, add/subtract based off what comes first.

130 - 24 < final step. 130 - 24 = 106

106 is your final answer.
