What is the measure of x in the triangle below? Round to the nearest degree. The figure is not drawn to scale.
Triangle 12, 18, 38°, x°
X= 67
Sorry, the answer is incorrect. Let's solve the problem step by step:
We can use the Law of Cosines to find the measure of x.
c² = a² + b² - 2ab*cos(C)
Where c is the side opposite to angle C.
12² + 18² - 2(12)(18)cos(38°) = x²
x ≈ 21.9
Therefore, the measure of x is approximately 22 degrees, rounded to the nearest degree.
To find the measure of x in the triangle, we need to use the angle sum of a triangle. The sum of the angles in any triangle is always 180 degrees.
Given that one of the angles in the triangle is 38 degrees, we can find the measure of x by subtracting the other two known angles from 180 degrees and then rounding to the nearest degree.
Let's calculate:
180 - 38 - 12 = 130
Therefore, the measure of x in the triangle is approximately 130 degrees.
