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)°

Answer:
i think the answer is (12*3.14 = 37.68cm is the circumference and 6^2*3.14 = 113.04cm2 is the area.)

Answer:
17.54 ft
Step-by-step explanation:
Moving along the line from (–4.2, –6.4, 4.5) to (7.1, 2.2, 5.8), x increases by 11.3, y by 8.6 and z by 10.3.
Applying the Pythagorean Theorem twice, we get
(length of clothesline) = √( 11.3² + 8.6² + 10.3²), or 17.54 ft.
