Answer:

AAA

Step-by-step explanation:

The answer is AAA because the other choices are all triangle congruence properties. However, AAA is not a triangle congruence property, hence, it is the odd one out. SSS stands for Side - Side - Side, AAA stands for Angle - Angle - Angle, RHS stands for Right Angle - Hypotenuse - Side and SAS stands for Side - Angle - Side.

In which triangle is the measure of the unknown angle, x, equal to the value of sin–1(StartFraction 5 Over 8. 3 EndFraction)?.

almond37 [142]

The triangle is a right-angled triangle with a perpendicular side of 5 and a hypotenuse of 8.3.

<h2 /><h2>Given to us</h2>

$\theta = sin^{-1}\dfrac{5}{8.3}$

as we know that sine for any angle is the ratio of its perpendicular to the hypotenuse, and trigonometry is only applicable to a right-angled triangle.

therefore,

$\theta = sin^{-1}\dfrac{5}{8.3}\\\\sin \theta=\dfrac{5}{8.3}=\dfrac{Perpendicular}{Hypotenuse}\\$
