Answer:
C.
THis is a right angle making it 90°
Therefore, 6x-15) + x = 90
Step-by-step explanation:
Answer:
63
Step-by-step explanation:
2 ways: 18/2 = 9 9 times 7 is 63
18 times 3 =54 plus 9 (because 18/2 is 9) is 63
Cos <span>θ = 0.5333
inverse cosine both sides of equation
cos⁻¹(cos </span>θ) = cos⁻¹(0.5333)
on left side, cosine cancel out
on right side use calculator in radian mode
θ = 1.0083
for the ttriangle, assuming c is the hypotenuse
pythagoras
a² + b² = c²
b² = c² - a²
b = √(c² - a²)
b = √(9² - 2²)
b = 8.77
Answer:
B is the answer
