Ainat [17]3 years ago
4 0

Answer:

  cot(theta) = 1/(-3/8)

Step-by-step explanation:

cot(theta) = 1/tan(theta) = 1/(-3/8)

_____

<em>Comment on the answer</em>

The parentheses are required. With them, the value is cot(theta) = -8/3. Without them, the value is cot(theta) = -1/24, which is not correct.

Even if the answer is typeset, it must be done in such a way as to make it clear what the numerator and denominator are:

\displaystyle\frac{1}{-\frac{3}{8}}

bekas [8.4K]

Answer:

134°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠XCA = ∠XAC .  Congruent angles

∠XAC = 1/2(46) = 23° .  because CE bisects ∠ C

∠XCA = 23°

180° - 23° - 23° = 134° .  Sum of all angles in a triangle is 180°
