Evaluate [ sin^2 θ - ( cos^2 θ ) (sin^2 θ) ] ^-1 for θ = 30°.
The value of this expression is :

7,24

step-by-step explanation:

x = 12

y = 1

for the points!

erica would now have 20 bottles of water because 26-6=20.

i hope this : )

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
