Question

Find the measure of the indicated angle to the nearest degree​

Answer 1

`\boxed{\sf sin\theta=(P)/(H)}`

`\\ \sf\longmapsto sin\theta=(38)/(53)`

`\\ \sf\longmapsto sin\theta=0.7`

`\\ \sf\longmapsto sin\theta=(1)/(1.4)`

`\\ \sf\longmapsto sin\theta=(1)/(√(2))`

`\\ \sf\longmapsto sin\theta=sin45°`

`\\ \sf\longmapsto \theta=45°`
