Answer:
82
Step-by-step explanation:
Sides AB and BC are equal, which means angle BAC and BCA have the same measure, as stated in the base angles theorem. Angle BAC is 49 degrees, so angle BCA must also be 49 degrees. The sum of all angles in a triangle is 180 degrees, so angles BAC, BCA, and CBA will add up to 180. Write this in an equation:
BAC+BCA+CBA=180
BAC and BCA both measure 49 degrees:
49+49+CBA=180
Solve for CBA
CBA=180-49-49
CBA=82

Y=1/4x+3 is the correct equation
Answer:
=-5ab
Step-by-step explanation:
Rewrite: -15 as 3*5
Rewrite: -5 *2*2 as 1*5
Rewrite: 10 *3 as 6*5
=6* 5ab +4 *5ab +3ab
Factor out common term 5ab
=5ab(6-4-3)
=-5ab
