c ≈ 16.7 ( to 1 dec. place ) → d
since triangle ABC is right use the cosine ratio to find c
cos33° =
= 
multiply both sides by c
c × cos33° = 14 ( divide both sides by cos33° )
x =
≈ 16.7 ( to 1 dec. place )
Answer:
Answer is c
Step-by-step explanation:
Solve for x
To solve for x, set the left hand side equal to 0 and solve for x with the quad equation
Answer:
x = 113
Step-by-step explanation:
Since the shape is a quadrilateral, the angles add up to 360 so:
x + 87 + 113 + 47 = 360
x + 247 = 360
x = 360 - 247
x = 113
