<span>sin(80°)= opposite/hypotenuse </span>⇒

hypotenuse = opposite/sin(80°) = 4/0.9848 ≈ 4.1 in. ← <span>to the nearest tenth.</span>

HELP!!!!!!!!!!!!!! I learned this two years ago and I don't remember how to do this anymore!!!!!!

Otrada [13]

So remember the acronym "SOH CAH TOA"

Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent

Opposite = Side that doesn't touch the angle
Adjacent = Side that touches the angle
Hypotenuse = Side that is across from the right angle

<h3>A.</h3>

So we see that side a doesn't touch angle $\alpha$ , hence making it the opposite side. And we see that side b is across from the right angle, making it the hypotenuse. <u>Using this info, $\sin \alpha = \frac{a}{b}$ </u>

<h3>B.</h3>

So we already know from part A that side b is the hypotenuse. And also since side c touches the angle, it is the adjacent.<u> Using this info, $\cos \alpha = \frac{c}{b}$ </u>

<h3>C.</h3>

Next, it has been established that side c is the adjacent and side a is the opposite side. <u>Using this info, $\tan \alpha = \frac{a}{c}$ </u>

Find m A. 10 B. 5 C.√53 D. 10√3/3

MArishka [77]

Answer:

$m = 10$

Step-by-step explanation:

Looking at the angles, we can see that this is a 30-60-90 triangle.

The side that is with the 30° angle and the 90° angle is represented by $x\sqrt{3}$ .

So let's find x.

$x\sqrt{3} = 5\sqrt{3}$

Divide both sides by $\sqrt{3}$ :

$x = 5$ .

Now the hypotenuse is always $2x$ (the leg with the 90° and 60° is just x.) So,

$2x = 2\cdot5 = 10$ .

Hope this helped!

Can someone solve n/7-12=5n+5 step by step pls

prohojiy [21]

Answer:

n=-7/2 I hate asking for things but can i have brainliest im trying to rank up.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

n/7−12=5n+5

1/7n+−12=5n+5

1/7n−12=5n+5

Step 2: Subtract 5n from both sides.

1/7n−12−5n=5n+5−5n

-34/7n−12=5

Step 3: Add 12 to both sides.

-34/7n−12+12=5+12

-34/7n=17

Step 4: Multiply both sides by 7/(-34).

(7/-34)*(-34/7n)=(7/34)*(17)
