the value of cos 15 is √3+1/2√2
explanation
cos (45-30)
=cos45*cos30+sin45*sin30
=1/√2 * √3/2 + 1/√2 * 1/2
=√6/4 + √2/4
=√6 + √2/4
=√3+1/2√2
'you use sine = opposite/ hypotenuse
you use cosine = adjacent/ hypotenuse
you use tan laws= opposite/adjacent
Answer:
17
Step-by-step explanation:
Let the smaller number = x
Let the larger number = y
y = 2x + 8
y - x = 25 Add x to both sides
y = x + 25 Substitute this into the first equation
x + 25 = 2x + 8 Subtract 8 from both sides
x + 25 - 8 = 2x Combine
x + 17 = 2x Subtract x from both sides.
17 = 2x - x Combine
17 = x
Option four
because if u solve it...
(c+2)6
=6c+2

Answer: A) high</h3>
Explanation:
Each set spans from 3 to 7 as the min and max. Since we're dealing with the same endpoints, we have perfect overlap.
