You would subtract 90% and 35% and get 55%. You subtract that by 20 and yiu will have 35% of the 90% mixture
Answer:
C + 88 = 180
-88 -88
C and B = 92
Since C is vertical to B that means both values are the same. Therefore the values of c and b is 92 degrees.
The function representing the price of the ring x years after 2000 is f(x) = (100 + 35)/100 *x + 590 = 135/100 *x + 590 = 1.35x + 590
i.e. f(x) = 1.35x + 590
The third angle is 29 degrees.
180 - 58 - 93 = 29
