x = 15  \sqrt{2}

y = 15  \sqrt{2}

klio [65]3 years ago

Answer:

x = y = 15\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{\sqrt{2} }{2} , then

sin45° = \frac{opposite}{hypotenuse} = \frac{x}{30} ( multiply both sides by 30 )

30 × sin45° = x , then

x = 30 × \frac{\sqrt{2} }{2} = 15\sqrt{2}

The triangle is a right isosceles triangle thus the legs are congruent, then

x = y = 15\sqrt{2}

Solve for v 3(2v+5=33 simplify as much as possible
vredina [299]

3(2v+5)=33

Simplify both sides of the equation

3(2v+5)=33

Distribute

(3)(2v)+(3)(5)=33

6v+15=33

Subtract 15 from both sides

6v+15-15=33-15

6v=18

Divide both sides by 6

6v/6=18/6

V= 3


I hope that's help !

Does the point (-5, 3) satisfy the equation y = x − 8?
o-na [289]
No. This is because you can plug it in and see if it is true. Meaning...
3=-5-8
3=-13
3 is not equal to -13. Therefore the point does not satisfy the equation
