How do you decide whether a number is a solution of an inequality

Mathematics

disa [49]4 years ago

Answer:

  • We can solve inequalities to find all values of the variable that make the inequality true. The idea is to get the variable all by itself on one side of the inequality sign so we can easily see the solutions to the inequality.
  • Hence for any given inequality and for any given number if we put that number in that inequality and see that the given inequality sign holds true than that number will be a solution of the inequality otherwise it is not an solution of the inequality.

Answer:

  7.28 miles

Step-by-step explanation:

Suppose the distance at closest approach is represented by x. Then the distance to the point of closest approach at the first sighting is ...

  d1 = x·tan(62°)

At the second sighting, the distance to the point of closest approach is ...

  d2 = x·tan(38°)

The difference of these distances is 8 miles, so we have ...

  d1 -d2 = 8 = x(tan(62°) -tan(38°))

Dividing by the coefficient of x, we find ...

  x = 8/(tan(62°) -tan(38°)) ≈ 7.2764 . . . . miles

The point of closest approach is about 7.28 miles from the landmark.

Answer:

Area = 90 units^2

Step-by-step explanation:

For the area of a triangle, we can simply use the following equation:

Area = ( 1 / 2 ) * Base * Height

We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.

Area = ( 1 / 2 ) * Base * Height

Area = ( 1 / 2 ) * 12 * 15

Area = 6 * 15

Area = 90

Hence, the area of our triangle is 90 units^2.

Cheers.

pishuonlain [190]
Since all triangles r equal to 180° 
123+41= 164
180-164=16

the measure of the third angle of the triangle is 16°
