Answer:
<ABC = 98.
Step-by-step explanation:
We know that the triangle is lying on a flat line, which is 180 degrees. We know that angle ABC and angle CBD are supplementary as they both use line ABD as their transversal.
Set up the equation (3 + 5x) + 82 = 180.
Solve for x, and you get 19.
Plug it back in to (3 + 5x), we get <ABC = 98.
15 is 9 more that j
Let is be the = sign.
Let more than be the + sign.
15 = 9 + j
23/30 can't be simplified any further because 23 is a prime number.
