The length of a in the triangle to the nearest tenth is 8.1 units.
<h3>How to find side of a triangle?</h3>
The side a of the triangle can be found using cosine formula.
Therefore,
a²= b² + c² - 2bc cos A
a² = 10² + 12² - 2 × 10 × 12 cos 42°
a² = 100 + 144 - 240cos 42
a² = 244 - 178.354758115
a = √65.6453
a = 8.10217871933
a = 8.1

Answer:
x = 143
Step-by-step explanation:
The chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, that is
x = 
(140 + 146) = 0.5 × 286 = 143
Times the sides and add them
