The top of a dam has an angle of elevation of 1.2 radians from a point on a river. measuring the angle of elevation to the top of the dam from a point 145 feet farther downriver is 0.8 radians; assume the two angle measurements are taken at the same elevation above sea level. how high is the dam? (round your answer to the nearest whole number.) ft

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
