Answer:

x \ge 15

Step-by-step explanation:

An isosceles ∆ has 2 equal sides. The perimeter of a ∆ is the sum of all its sides.

Given that the perimeter of the triangle above is "at least 137 ft", this means the sum of all its sides is equal to or greater than 137 ft.

Thus, using inequality, this can be represented as:

2(2x + 7) + 4x + 3 \ge 137

Solve for x

4x + 14 + 4x + 3 \ge 137

Add like terms

8x + 17 \ge 137

Subtract 17 from both sides

8x + 17 - 17 \ge 137 - 17

8x \ge 120

Divide both sides by 8

\frac{8x}{8} \ge \frac{120}{8}

x \ge 15

Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.
