2x+4y = 1                     
3x- 5y = 7
Multiply both equation by a number to get rid of one variable I used y because it had opposite signs so multiply top equation by 5 and bottom by 4
you get,
10x + 20y = 5
12x  - 20y = 28
solve the equation we get,
22x = 33 
x = 33/22
x = 1.5
substitute this value in other equation to get y 
2x + 4y = 1
2(1.5) + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4
y = -0.5
so answer is x = 1.5 and y = -0.5
( 1.5, -0.5)

How do I solve this? Thank you.

Answer:

Heyya little student!

Sin means \frac{opposite }{hypotenuse}

5 is the hypotenuse (its opposite to 90 degrees )

So, sin β would be:-

the side opposite to the angle β divided by the hypotenuse of the triangle.

The side opposite to β is 4

and as I said earlier, the hypotenuse is 5

<h2>So, sin β would be:-</h2><h2>\frac{4}{5}</h2>

I hope it helped you!

I need this by tonight help !!?
LUCKY_DIMON [66]
Since the measure of angles adds up to 180, you should add all of the known angles up and subtract from 180 to find the missing angle. For example: 47+69=116
and
180-116=64 so the measure of the missing angle is 64 degrees

85+42= 127 
180-127=53 s the measure of the missing angle is 53
