Answer:
∠ A = 72°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ ECD = 180° - (90 + 54)° = 180° - 144° = 36°
∠ ACB = ∠ ECD = 36° ( vertical angles )
Since AC and BC are congruent then Δ ABC is isosceles, thus the base angles are congruent, that is
∠ A = ∠ B
∠ A = = = 72°
Answer:
c
Step-by-step explanation:
(12 x 120)/ 3.87 x 3.35=c
You only have to check the first few, since as the factors increase, the numbers go up faster. Checking, 3 and 9 both divide 108. The answers are 3 and 9.
Water carried = 1/2 gallon
Water drank =
= 2/3 of 1/2 gallon
= 2/3 × 1/2
= 2/6
= 1/3 gallon
