Step-by-step explanation:

<u>Triangles</u>

An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.

The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:

8x+3=67

Reducing:

8x=67-3=64

Solving:

x=64/8

x=8

It is given that in △ABC, AD ⊥ BC. Using the definition of sine with angle C in △ACD results in sin(C) = . Using the multiplicat

We see here in the diagram that the base is a. We know this because the height is perpendicular to it. We also know the height is bsin(C) which, when replace h for bsin(C) and a for the base, we get A=absin(C), which is the second option.
