Answer:
Sine Formula or Sine Rule :
BC / sinA = AC / sinB
60 / sinA = 84.95 / sin(115°)
60 / sinA = 84.95 / 0.91
60 / sinA = 93.7
sinA = 60 / 93.7
sinA = 0.64
A = arc(sin0.64)
A = 39°48'30"
A ≈ 40°
Hence, the value of angle BAC is <u>40°</u>
- <u>40°</u> is the right answer.

At the 2/8 part, just use the quadratic formula. If you use it, you should get the other two zeroes:
Answer:
x = 30
Step-by-step explanation:
-2x + 10 +4x=70
-10 -10
-2x + 4x = 60
2x = 60
/2 /2
x = 30
The answer is 0.6 . 3 divide 5 is 0.6
Step:6x+12y-6z+7x+7y-28z
Answer:13x+19y-34z
The answer would be 28 feet, to get area you do length times width, 7 x 4 = 28
