The picture. and answer 1-6. please hurry

satela [25.4K]

Answer:

Step-by-step explanation:

From the figure attached,

1). Sin(D) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{EF}{DF}$

= $\frac{24}{26}$

= $\frac{12}{13}$

2). Cos(D) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{ED}{DF}$

= $\frac{10}{26}$

= $\frac{5}{13}$

3). tan(D) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{EF}{DE}$

= $\frac{24}{10}$

= $\frac{12}{5}$

4). sin(F) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{DE}{DF}$

= $\frac{10}{26}$

= $\frac{5}{13}$

5). cos(F) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{EF}{DF}$

= $\frac{24}{26}$

= $\frac{12}{13}$

6). tan(F) = $\frac{\text{Adjacent side}}{\text{Adjacent side}}$

= $\frac{DE}{EF}$

= $\frac{10}{24}$

= $\frac{5}{12}$
