THEOREM:
•<u> </u><u>Supplementary angle</u> —» The sum of two angles is equal to 180°.
ANSWER:
By supplementary angle property,
So, m∠QRS + m∠ABC = 180°
- m∠QRS + 41° = 180°
- m∠QRS = 180° - 41°
- m∠QRS = 139°
Answer is x = 1 & y = 2
the answer can be found using math-way
-3 (x - 5) - 8 (y + 2) + (-3) (6 - 4b)
First, simplify your brackets. / Your problem should look like: -3 (x - 5) - 8 (y + 2) + -3 (6 - 4b)
Second, simplify. / Your problem should look like: -3 (x - 5) - 8 (y + 2) - 3 (b - 4b)
Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19
Answer: -3x - 8y + 12b - 19 (D)
