Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
Step-by-step explanationdomain and range of 1/(4-9x) is second one.
Just look it up you can find the answers you are looking for
180 min is 3 hrs becuz 180 min by 60 min is equal to 3 hrs 180÷60=3
The answer remains as is, or you could do it this way: 1(9 + 8b²).
