Answer:
3/5
Step-by-step explanation:
sin theta=opposite/hypotenuse
4/5=opposite/hypotenuse
therefore opposite=4 and hypotenuse=5
for adjacent
using pythagoras theorem
a^2+b^2=c^2
opposite^2 + adjacent^2 =hypotenuse^2
4^2 + adjacent^2 =5^2
16 + adjacent^2 =25
adjacent^2 =25-16
adjacent =
adjacent=3
cos theta=adjacent/hypotenuse
=3/5
therefore the value of cos theta is 3/5

Answer:
x= 1/12
Step-by-step explanation:
Hi there!
2x + 1/2= 2/3
You're trying to solve for x. In order to do that you need x by itself. You have to subtract 1/2 from both sides. When you do this you get 2/3 - 1/2. You can't just subtract them, remember, you have to find a common denominator.
2/3
1/2
The common denominator for these two fractions would be 6. to get 2/3 to a denominator of 6, you have to multiply it by 2/2. To get 1/2 to have a denominator of 6, you have to multiply it by 3/3. You then get...
4/6
3/6
Now you can subtract straight across. 4/6-3/6 is equal to 1/6. Ply it back into the equation and you have 2x=1/6. Now you have to divide 2 on both sides. To do this you divide 2x by 2 to get x. Then, you divide 1/6 by two.
Remember when dividing fractions you must flip the second fraction and multiply. What I mean is...
1/6 divided by 2 is the same thing as 1/6 x 1/2. We flipped 2 to get 1/2 and then we multiply straight across. When you do this you get an answer of 1/12.
x=1/12
I really hope this helps! :)
