3<br> Solve for x. Round answer to the nearest tenth.<br> X<br> 759<br> 17

QveST [7]

Answer:

x ≈ 4.6

Step-by-step explanation:

Reference angle = 75°

Opposite side to reference angle = 17

Adjacent side = x

Applying TOA:

Tan 75 = opp/adj

Tan 75 = 17/x

Multiply both sides by x

x*Tan 75 = 17

Divide both sides by Tan 75

x = 17/Tan 75

x ≈ 4.6

Find the exact circumference of a circle with the given radius.

11Alexandr11 [23.1K]

Answer:

$6.5\pi\ in$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=3\frac{1}{4}\ in$

Convert to an improper fraction

$r=3\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}\ in$

substitute

$C=2\pi(\frac{13}{4})$

$C=\frac{13}{2}\pi=6.5\pi\ in$
