45 Pts!

Answer 1

`\\ \tt\hookrightarrow cos^(-1)(0.5)`

`\\ \tt\hookrightarrow cos^(-1)\left((1)/(2)\right)`

`\\ \tt\hookrightarrow 60°`

Fact about cosine(cos)

`\\ \tt\hookrightarrow cos\theta=(Base)/(Hypotenuse)`

Answer 2

Explanation:

no calculator req

cos 60 is 0.5

so cos inverse of 0.5 os 60°
