Let l be the length of the patio, since the area is 80 feet² we get that:
Solving the above equation for l we get:
Answer: 8.9 feet.
Answer:
100°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°
∠ECD = 40° ( vertical angle to ∠ACB )
Since CE ≅ ED then ΔCDE is isosceles and
∠CDE = ∠ECD = 40°
∠E = 180° - (40 + 40)° = 180° - 80° = 100°
Divide the 2.3 by the 12 to move it to the right of the equal sign and make it cancel out on the left side.
Answer is y = 5.23
That's rounded to the hundredths place.
