Answer:
BC ≈ 4.0
Step-by-step explanation:
∠ DCA = 180° - 70° = 110° ( adjacent angles )
∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle
∠ DAC = 180° - 140° = 40°
Using the Sine rule in Δ ACD to find common side AC
=
( cross- multiply )
AC × sin40° = 15 × sin30° ( divide both sides by sin40° )
AC =
≈ 11.668
Using the cosine ratio in right triangle ABC
cos70° =
=
=
( multiply both sides by 11.668 )
11.668 × cos70° = BC , then
BC ≈ 4.0 ( to the nearest tenth )
This should be the answer
y= 7/4x + 14
Answer:
5/12
Step-by-step explanation:
2 2/5 = 12/5 so its reciprocal is 5/12
Reciprocals are fractions that are basically "flipped". You flip the denominator to the numerator and vice versa.
I believe it is 2 feet because area is base multiplied by height. So, 3 x 2/3 is 2.
