Solve the triangle for x.
Damm [24]

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°

In the left/right direction, your circle (at it's biggest point) goes from -5 to 5
the middle of -5 and 5 is 0
so the center of your circle should have a x = 0
in the (x , y) point

the only option that has
(0, something)
is C
Therefore your answer is C
