The following are angles in a convex quadrilateral: Angle A = 34 degrees Angle B = 108 degree Angle C = 65 degrees What is the measure of the missing angle?

Answers

In a quadrilateral all angels must equal 360 degress. So by adding your angels up and then subtracting them from 360, you will find the missing angle. 

34 + 108 + 65 = 207 

360-207 = 153 

Your unknown angle is 153 degrees
Well since it is a quadrilateral, the degrees equal 360. So add 108 + 34 + 65 = 207. Then subtract 207 from 360. 360 - 207 = 153. So 153 is your missing angle. To check just add 153 + 65 + 34 + 108 = 360.

Right angled triangle calculation.  the opposite is 150mm  and the only known angle is the right angle how can i calculate the other two sides and angle??

Answers

You can't.  One side and one angle is never enough to define a unique triangle.

If the side opposite the right angle is 150mm, the other 2 sides could be . . .

-- 75 and 129.9
-- 100 and 111.8
-- 110 and 101.98
-- 120 and 90
-- 130 and 74.83
-- both 106.07

or any one of an infinite number of other possibilities.

You need to know one more side, or one more angle.

Consumption of fast food is a topic of interest to researchers in the field of nutrition. An article reported that 1880 of those in a random sample of 6765 U.S. children indicated that on a typical day, they ate fast food. Estimate p, the proportion of children in the United States who eat fast food on a typical day. (Round your answer to four decimal places.)

Answers

Answer:

the proportion is 0.2779, that is a 27.79%

Step-by-step explanation:

The article reported that 1880 children ate fast food from a sample of 6765 children. We can use the rule of three to find the proportion of children that ate fast food

  • from 6765 we have 1880 children that ate fast food
  • from 100 children we have 1880 * ((100)/(6765)) = 27.79 children that ate fast food

that gives us that a 27.79% of the children ate fast food on a typical day. We can obtain the proportion by dividing the percentage by 100, that gives us a proportion of 27.79/100 = 0.2779.
