Answer:
x= 6 1/2 or 6.5
Step-by-step explanation:
4^x-5 =8
2^2(x-5) =2^3
since the base is equal, the powers are equal
2(x-5) = 3
2x - 10 = 3
2x = 3 + 10
2x = 13
2x/2 = 13/2
x = 6 1/2 or 6.5
The ratios of sin x° and cos y° are 15/8.
We have given that,
Use the image below to answer the following question.
We have to determine to find the value of sin x° and cos y°.
By applying Pythagoras theorem in the triangle given in the picture,
<h3>What is
the Pythagoras theorem?</h3>
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying the sine rule in the given triangle,
sin(x°) = Opposie side/hypotenous
= 15/17
cos(y°) = Adjucent side/hypotenous
= 8/17
The relation between the ratio of sin(x) and cos(x) will be,


Therefore the ratios of sin x° and cos y° are 15/8.

4 to 7......add them = 11
4/11 * 33 = 132/11 = 12
7/11 * 33 = 231/11 = 21
Answer:
it would be x=17 1/2
Step-by-step explanation:
i am going to go a little more into detail.
you would first have to divide each side to isolate the variable
x=5/2/7
simplifying steps:
you would have to change the 5 into 5/1
5/1÷2/7
now you have to keep the first number, change the sign, and then flip the last number, AKA KCF
5/1*7/2
35/2
and you can simplify this into a mixed number
17 1/2
hope this helps! have a nice day :)
