Answer:

B. sine

Step-by-step explanation:

In the given case you would use sine

sin = opposite / hypotenuse
sin 47 = y/11
y = 11 sin 47
y = 8.0 (rounded)

Using cosine or tangent you wouldn't be able to find the value of y as the value of x is unknown

GIVEN:

p = y, b = x, h = 11, angle = 47°.

ANSWER:

We will use sin function to find the value of y,

so, sin47° = p/h

sin47° = y/11

y = sin47° × 11

y = 0.73135370 × 11

y = 8.03 or 8.0 rounded.

So, Correct choice - [B] Sine.

10n-4=126

Step-by-step explanation:

I hope this is right, so number would be a variable (n) because we don't know what said number is.

if your multiply that by 10 then put the 10 next to variable, like usual. at least that's what I do.

four less would be saying to subtract 4

and the final answer is 126
