To transform the left side of the equation into the right side under the interval (0 < θ < π/2), the missing trigonometric identity to complete the equation is cos2 θ = 1- sin2 θ. This is a trigonometric identity specifically under the <span>Pythagorean Identities</span>
Answer:
too long, sorry got my own work to do :|
Step-by-step explanation:
625÷1/4= 156.25
25x2=50
156x2= 312
312.50= 312.5= 312 1/2
Answer:
QR = 5
Step-by-step explanation:
Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is
= 
, then
= 
( cross- multiply )
9QR = 45 ( divide both sides by 9 )
QR = 5
Answer:
the first one
Step-by-step explanation:
its right because you have to try and solve it out to get the answer so u subtract 4 the divide by 10 to get r= 8
