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
Answer:
-138
Step-by-step explanation:
58.5% since it’s 400 total and you want a percent 400\4 = 100 so 234/4 = 58.5
Answer:
5000000
Step-by-step explanation:
10^6 = 10 x 10 x 10 x 10 x 10 x 10
10^6 = 1000000
5 x 10^6
= 5 x 1000000
= 5000000
Y = 3x - 2....so we sub in 3x - 2 for y in the other equation
-3x + y = -2
-3x + (3x - 2) = -2
-3x + 3x = -2 + 2
0 = 0
there is infinite solutions to this problem
