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.
-1.5 !! this is easy hope this helps
It would be D: 181
3 17
---- = ------
32 X
Then you would cross multiply and divide.
Answer:
-35, 1493
Step-by-step explanation:
p(x) = 2x⁴ + 3x³ - 9x² + 16x + 13
p(-3) = 2(-3⁴) + 3(-3³) - 9(-3²) + 16(-3) + 13
-3² = 9
-3³ = -27
-3⁴ = 81
p(-3) = 2(81) + 3(-27) -9(9) - 48 + 13
p(-3) = 162 - 81 - 81 -48 + 13
81 + 81 = 162 therefore 162 - 81 - 81 cancels
-48 + 13 = -35
p(5) = 2(5⁴) + 3(5³) - 9(5²) + 16(5) + 13
5² = 25
5³ = 125
5⁴ = 625
p(5) = 2(625) + 3(125) - 9(25) + 80 + 13
p(5) = 1250 + 375 - 225 + 93
p(5) = 1250 + 150 + 93
p(5) = 1493
