Answer:
x ≈ 22.62°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = = , then
x = ( ) ≈ 22.62° ( to the nearest hundredth )
Answer : x = 14 and y = 3
Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = ← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
Answer:
x = ± 2
Step-by-step explanation:
Given
12 - x² = 0 ( add x² to both sides )
12 = x² or
x² = 12 ( take the square root of both sides )
x = ±
= ± = ± 2
1.5 is the answer too your question sir thanks.
