Answer:
its the first choice
Step-by-step explanation:
Answer:
angle ABC= 47°
angle CAD= 38°
Step-by-step explanation:
angle ABC= 180-(49+84)= 47°
because all angles in a traingle add up to 180°
angle ACD= 180-84= 96°
because angle on a straight line add up to 180°
so, angle CAD= 180-(46+96)= 38°
because all angles in a traingle add up to 180°

Answer:
D
Step-by-step explanation:
First, let's find <em>x</em>.
We know that one of the angles is 30. The side opposite to than angle is 11, and <em>x</em> is the adjacent side to it. Therefore, we can use the trig function tangent.
Recall that:

Plug in 30 for the angle, 11 for the opposite, and <em>x</em> for the adjacent. Solve for <em>x</em> by cross-multiplying:

From the unit circle, recall that tan(30) is equal to one over the square root of 3. Thus:

Now, we can use the Pythagorean Theorem to find <em>y</em>. <em>y</em> is the hypotenuse. Thus:
