Question

Help me i can’t figure it out

Answer 1

Answer:

The answer is option B

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find y

To find y we use tan

tan∅ = opposite/ adjacent

From the question

$\frac{7 \sqrt{2} }{2}$ is the adjacent

The opposite is y

So we have

$\tan(45) = \frac{y}{ \frac{7 \sqrt{2} }{2} }$

But

$\tan(45) = 1$

That's

$1 = \frac{y}{ \frac{7 \sqrt{2} }{2} }$

Cross multiply

We have the final answer as

$y = \frac{7 \sqrt{2} }{2}$

Hope this helps you
