Question

Triangles and Trigonometry help? Medal. (Image attached)

Answer 1

Use Pythagorus' Theorem. In a right-angled triangle like this \[8^{2} + 10^{2} = x ^{2}\]
\[x ^{2} = 164\]
\[x = \sqrt{164} \]

I put 'sqrt 164' into google to get about 12.8 for this number.

Answer 2

Yeah, I did that and understand that, but they want me to find the angle y

Answer 3

Saw that then forgot.

tan y = 8 / 10 -> arctan 8/10 = 0.674740942 radians or 38.66 degrees
tan z = 10/8 -> arctan 1.2 = 0.876058051 rad or 50.19 degrees

Again, I used google.
