Answer:
m∠ABC = 68°
m∠DEF = 112°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees (they form a straight line).
If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:
- (6x + 8) + (12x - 8) = 180
Combine like terms.
Divide both sides by 18.
Find the measure of each angle by substituting 10 for x into both expressions for the angles.
m∠ABC = (6x + 8)°
m∠DEF = (12x - 8)°
No because 8x8x8 is 516 and to find exponent is if it is 3 as exponent you times it by itself 3 times so the answer is no he is wrong
Answer:
16= 4²
25= 5²
36= 6²
49= 7²
64= 8²
81= 9²
so, third option is correct I.e. 49
hope it will help....
Answer:
18
Step-by-step explanation:
2x+y=6
y=3x+4
