Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet
.60 * 42 = 25.2
So, he/she would have answered 25 questions correctly.
There is one solution, (0,4) is your answer
Note that x = 0, y = 4
(4) = 1/3(0) + 4
4 = 0 + 4
4 = 4 (true)
3(4) - (0) = 12
12 - 0 = 12
12 = 12 (true)
There is one solution, (0,4) is your answer
hope this helps
