A. A complementary angle is an angle that, with another angle, adds up to 360°. If m∡A = 77°, its complementary angle must be 283° because 360-77=283.
b. If two different angles are complementary to the same angle, they must have the same measure, because only one number can add with the one number to get the same answer.
Hope this helps!
Answer:
x=−6
Step-by-step explanation:
<u>Step 1: Simplify both sides of the equation.</u>
3x−7-2/3(9x−6)=15
3x+−7+−6x+4=15(Distribute)
(3x+−6x)+(−7+4)=15(Combine Like Terms)
−3x+−3=15
−3x−3=15
<u>Step 2: Add 3 to both sides.</u>
−3x−3+3=15+3
−3x=18
<u>Step 3: Divide both sides by -3.</u>
−3x/−3=18/−3
x=−6
Answer:
x=-2
Step-by-step explanation:
2x+1=(-3)
-1 on both sides
2x=-4
÷2 on both sides
x=-2
