Find the size of angle xyz give your answer to 3 significant figures

KengaRu [80]

Answer:

68.2°

Step-by-step explanation:

This is a right triangle, so we can use SIN,COS,TAN to solve for the angle.

We want ∠YXZ

THe side opposite to the angle is given as 20

The side adjacent to the angle is given as 8

Which trig ratio relates "opposite" and "adjacent"??

It is Tan!!

Thus, we can write:

$Tan(\angle YXZ)=\frac{20}{8}\\Tan(\angle YXZ)=\frac{5}{2}\\Tan(\angle YXZ)=2.5\\\angle YXZ = ArcTan(2.5)\\\angle YXZ = 68.2$

THis is the angle

68.2°

How to figure out answer ?

spin [16.1K]

$\sin 45=\dfrac{y}{11\sqrt6}\\
\dfrac{\sqrt2}{2}=\dfrac{y}{11\sqrt6}\\
2y=11\sqrt{12}\\
y=\dfrac{11\sqrt{12}}{2}\\\\
\tan 60=\dfrac{x}{y}\\
\tan 60=\dfrac{x}{\dfrac{11\sqrt{12}}{2}}\\
\sqrt3=\dfrac{2x}{11\sqrt{12}}\\
2x=11\sqrt{36}\\
2x=66\\
x=33 \Rightarrow D
