Answer:
Step-by-step explanation:
In this math, we will be using the law of cosine.
a2 = b2 + c2 − 2bc cosA
This is to note that a here is actually x
a= x
b = 10
c = 9.4
cosA = cos20°
[tex]a = \sqrt{b^{2} +c^{2} - (2bc*cosA) }\\\\a= \sqrt{100 +88.36 - (188- 0.94)} \\\\a = \sqrt{1.3}\\\\a = 1.14[/tex]
