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 $18x-7$

The Gobi Desert spans across Mongolia and China. It specifically runs across northwestern and northern China and Southern Mongolia. The Gobi is a large desert region in Asia and is a rain shadow desert formed by the Himalaya range blocking rain-carrying clouds from the Indian Ocean from reaching the Gobi territory. The Gobi is most notable for it being the location for several important cities in the Silk Road and as part of the Great Mongol Empire.
