First, it's worth noting that angles on a straight line sum to 180°. We can use this information to find out the value of y:
180-52-59=69
y=69°
Another rule is that the angles in a triangle sum to 180° as well. This means that we can now find out x:
63+y+x=180
63+69+x=180
180-63-69=x
x=48°
The expression 6x^2-1 cannot be factored or simplified any further.
Answer:
If C is the 90 degree angle, then side c is the hypotenuse.
c^2 = a^2 + b^2
b = sqr rt (c^2 - a^2)
b = sqr root (625 -576)
b = sqr root (49)
b = 7
