Assume that θ is a positive acute angle. \text{Given: } \cos\theta=\frac{24}{25}
Given: cosθ=
25
24


\text{Find: }\cos2\theta
Find: cos2θ

b.-4 units

all you   do is count how many times you move

just get this app called photo math it should be able to do those

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

hi there!

the answer is: 2 and -2

step-by-step explanation:

case 1: an absolute value of positive number will still be a positive number

so absolute value of 2 is 2

case 2: an absolute value of negative number will be positive number so absolute value of -2 is 2
