Answer:

x = 55\\y = 30\\

Step-by-step explanation:

<u><em>Finding x:</em></u>

4x - 100 + x + 5 = 180 <em>(Angles on a straight line)</em>

5x - 95 = 180

5x = 180 + 95

5x = 275

<em>Dividing both sides by 5</em>

x = 55

<em><u>Finding y:</u></em>

2y + 3y +30 = 180 <em>(Angles on a straight line)</em>

5y = 180-30

5y = 150

<em>Dividing both sides by 5</em>

y = 30

Answer:

X=55°

Y=30°

Step-by-step explanation:

2y=x+5

Y=1/2x+2.5

3y+30=4x-100

3(0.5x+2.5)+30=4x-100

1.5x+7.5+30=4x-100

4x-1.5x=137.5

2.5x=137.5

X=55°

Y=30°

Ruby conducted a survey and found that 5/6 of her classmates have a pet and 2/3 of them are dogs what fraction of her classmates
lina2011 [118]
This is how I would solve it, I would act as if there were 36 people in the class.
36÷6=6×5=30
30÷3=10×2=20
20/36=10/18=5/9
You could also try another number such as 24;
24×(5÷6)=20
20×(2/3)=13.3(3 repeating)
13.333/24=5/9
5/9 people have dogs.
Tell me if this helps.

How do you solve this
Dmitriy789 [7]

By definition of the trig functions,

\sin30^\circ=\dfrac y{16}

\cos30^\circ=\dfrac x{16}

We have \sin30^\circ=\dfrac12, so y=8, and \cos30^\circ=\dfrac{\sqrt3}2, so x=8\sqrt3.

Just to check: we should have

x^2+y^2=16^2

by the Pythagorean theorem. Indeed,

8^2+(8\sqrt3)^2=4\cdot8^2=2^2(2^3)^2=2^8=(2^4)^2=16^2
