First, you would have to add d to both sides to get rid of it
x+d=ab+c/b
Then you would multiply b by both sides to get rid of the b in the denominator
x+d(b)=ab+c
After that, you would subtract c from both sides
x+d(b)-c=ab
Then you would divide both sides by a
x+d(b)-c=b

A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72
b=4a+c
b=4(18)+36
b=72+36
b=108
your x-intercept is 3 and I don't know why I have to do 20 characters for an answer that involves 3 words and 1 number
Answer:
12cos59, about 6.18
Step-by-step explanation:
cos59 = x/12
(adjacent/hypotenuse)
x = 12cos59
plugging this into a calculator gets you about 6.18
2400 divided by 44% which is 1056.
