Step-by-step explanation:
Answer:
d) 86.2 degrees
x = 86.20°
Attached is the image used in the question;
Step-by-step explanation:
Applying the law of cosine;
Cos C = (a² + b² - c²)/2ab
Where;
Angle C = x
c = 13 ft
b = 9ft
a = 10ft
Substituting into the equation;
Cos x = (10² + 9² - 13²)/(2×10×9)
Cos x = 0.0667
x = cos⁻¹(0.0667)
x = 86.20°
First, we would have to figure out what is 1. I divided 432 by 9 and got 48. Then, I used that 48 and multiplied it by 4. I got 192. The answer could be 192. Tell me if this is wrong.
