More information is needed to answer your question.
The answer provided below is on the assumption that |AD| is an angle bisector of <BAC, by Sine rule
Also,
But,
Thus,
But,
are supplementary angles, hence they are equal.
Therefore, x = 27

Answer:
Step-by-step explanation:
There are two similar triangles in this figure. The small one has a base of 6 and a height of 3.
The bigger triangle has the smaller one included in it, so you must add together the bases, 6 and x, and the heights, 3 and 4, to get the proportion.

Answer:
2.8¢, true
Step-by-step explanation:
The value of copper in a penny is reportedly about ...
(0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028
Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.
The claim is true.
The angles of a triangle add up to 180 degrees
180 - 80 = 100
Both of the unknown angles are the same. So...
100/2= 50
X = 50 degrees
