The measures of the three angles of a triangle are given by 18x − 7, 12x + 9, and 4x. What is the measure of the largest angle?

Goryan [66]

Answer:

The greatest angle is $18x-7$

Explanation:

According to angle sum property of a triangle, sum of all the angles of a triangle is equal to $180$ °.

The given angles of a triangle are $18x-7,12x+9,4x$

Therefore,

$18x-7+12x+9+4x=180$ °

$34x+2=180$ °

$34x=178$ °

$x=\frac{178}{34}=\frac{89}{17}$

$18x-7=18(\frac{89}{17})-7=\frac{1602-119}{17}=\frac{1483}{17}$ ≈ 87.2°

$12x+9=12(\frac{89}{17})+9=\frac{1068+153}{17}=\frac{1221}{17}$ ≈ 71.8°

$4x=4(\frac{89}{17})=\frac{356}{17}$ ≈ 20.9°

Therefore, greatest angle is $18x-7$

List two human activities and two natural events that can cause a large increase in the rate of soil erosion.

tekilochka [14]

Two human activities that increase the rate of erosion include farming and deforestation. Both make the top cover of the soil loose making it very easy for it to be carried away by agents of erosion such as wind and water. On the other hand, two natural events that can lead to increased <span>erosion rate include floods and earthquake.</span>
