Answer:
Step-by-step explanation:
Hence cot θ =cosθ / sinθ < 0 and sin θ < 0 that means that cos θ >0 hence θ lies on IV quadrant.
Hope this helps!
Answer:
9 units
Step-by-step explanation:
using distance formula
Answer:
The answer is 256 + 336 = 592. Although in reality you couldn't play soccer that much in two days.
Given: ABCD ∥gram,
BK ⊥ AD , AB ⊥ BD
AB=6, AK=3
Find: m∠A, BK
To proof
as given BK ⊥ AD
thus ΔABK is a right triangle.
thus by using the pythagoras theorem
we have
AB² = BK² + AK²
BK² = AB ²- AK²
= 6² - 3²
= 36 - 9
= 27
Hence
BK = <u>
unit</u>
Now find the value m∠A
by using the trignometric function
FORMULA
cosA = 
cosA = 
= 
m∠A = 60°
hence proved
Answer: B) 4 & 1/6
Nice work on getting the correct answer.
============================================================
Explanation:
x is opposite the marked acute angle
5 is opposite the corresponding acute angle
So x and 5 are proportional to each other. We can form the ratio x/5
Similarly, 10 and 12 are proportional to one another. We can form the ratio 10/12.
Set those ratios equal to each other and solve for x
x/5 = 10/12
12x = 5*10 ... cross multiply
12x = 50
x = 50/12 ...... divide both sides by 12
x = (25*2)/(6*2)
x = 25/6
x = (24+1)/6
x = 24/6 + 1/6
x = 4 + 1/6
x = 4 & 1/6 which shows why <u>choice B</u> is the answer.
Side note: 25/6 = 4.167 approximately
