cos (B) = 3/(3sqrt(2))
B = cos ^-1(3/(3sqrt(2)))
B = 45 degrees
Answer:
x = sqrt(147)
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
x^2 = 147
Take the square root of each side
sqrt(x^2) = sqrt(147)
x = sqrt(147)

Answer:
Step-by-step explanation:
x° + y° = 180°
2y° - 0.5x° = 180°
y° = 108°
x° = 72°
