The height of a triangle is 4 inches greater than twice its base. the area of the triangle is no more than 168 in.² which inequality can be used to find the possible lengths, x, of the base of the triangle?
a. x(x+2)=> 168
b. x(x+2)=< 168
c. 1/2x(x+4)=< 168
d. 1/2x(x+4)=> 168

Correct option: B

When we say a is no more than b, we express this in a mathematical language as follows:

In this inequality, we know that the area of the triangle is no more than 168 in². In other words, if the area is named , then:

We also know that the height of a triangle is 4 inches greater than twice its base. Translating this in a mathematical language:

From geometry, we know that the area of a triangle is given by:

Matching (1), (2) and (3):

Since the length of the base of the triangle is , then

Finally, correct option is B.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
