Solve 5 tan x = 5√(3) for 0° ≤ x ≤ 180°.<br><br> a. 60°<br> b. 150°<br> c. 30°<br> d. 120°
ladessa [460]

Answer:

\boxed{a.\:\:\:60\degree}

Step-by-step explanation:


The given trigonometric equation is


5\tan(x)=5\sqrt{3} for 0\degree \le x\le 180\degree.


We divide through by 5 to get;


\tan(x)=\sqrt{3}


We take the inverse tangent of both sides to obtain;


x=tan^{-1}(\sqrt{3})


x=60\degree


Since the tangent ratio is positive, it means x could also be in the 3rd quadrant. But this is outside the given range.


Therefore the correct answer is A

∠3 is a complement of ∠4, and m∠3=46°. Find m∠4.
Eduardwww [97]

Answer:

m < 4 = 44 degrees

Step-by-step explanation:

Here, we want to find the value of the given angle.

Mathematically, when two angles are complement of each other, they add up

to be 90 degrees. These angles are termed complementary angles.

Thus, by mathematical convention is this present case;

m <3 + m< 4 = 90

46 + m<4 = 90

m<4 = 90-46

m< 4 = 44 degrees
