Answer:
x = 15.6
Step-by-step explanation:
In order to find x we use the cosine rule, since we have all two sides and an angle
So we have
x² = ZX ² + XY² - 2(ZX)(XY) cos X
From the question
ZX = 13
XY = 8
X = 93°
Substituting the values into the expression we have
x² = 13² + 8² - 2(13)(8)cos 93
x² = 169 + 64 - 208 cos 93
x² = 233 - 208 cos 93
x² = 243.885
Find square root of both sides
x = 15.616817
We have the final answer as
x = 15.6 to the nearest tenth
