First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.

To determine the common ratio of the geometric sequence, divide the second term with the first term. 480 divided by 768 equals 5/8. Further, the ratio of the third and second terms may be used to check the consistency of the common ratio. The ratio is also 5/8. Thus, the common ratio is 5/8.
Let x and y represent the two numbers. The equation matching the word description is ...
x +4y = 25
