Answer:

20 ,70

Step-by-step explanation:

Complementary angles sum up to 90

2x + 4x + 30 = 90

     6x  + 30 = 90

Subtract 30 from both sides

6x = 90 - 30

6x = 60

x = 60/6

x = 10

2x = 2*10 = 20

4x +30 = 4*10 +30 = 40 +30 = 70

The masses to the nearest kilogram of nine men were:
serious [3.7K]

Answer:

82 kg

Step-by-step explanation:

To find the mean of a set of values, we must add them up and divide by the number of values.

Step 1, adding the values:

75+68+78+82+85+90+88+92+76=\\734

Step 2, dividing by the # of terms:

There are 9 terms in total.

\frac{734}{9} =\\81.556

To the nearest kilogram, we can round 81.556 into 82.

The mean mass of the 9 men was \fbox{82} kg.
