sec y° = q over r ⇒ 1st answer
Step-by-step explanation:
Let us revise some trigonometry ratios
tanα = secα =∵ sin y° =
∵ tan y° =
- Substitute tan(y) by
∴ =
- To find sec y° divide by sin(y)
∵ ÷ sin(y) = ÷
- Change (÷) to (×) and reciprocal the term after (÷)
× = ×
- Simplify the left hand side by divide up and down by sin(y)
and the right hand side by divide up and down by 7
∴ =
∵ sec y° =
∴ sec y° =
∴ sec y° = q over r
