What is the Value of x+y ? PLZ Help ASAP
Natalija [7]
ANSWER

x + y = 60

EXPLANATION

Method 1

Vertically opposite angles are equal, therefore

3x + 55 = 85

This implies that,

3x = 85 - 55

We simplify to get,

3x = 30

Dividing through by 3 gives,

x = 10

Also,

2y - 5 = 95

This implies that,

2x = 95 + 5

We simplify the right hand side to get,

2x = 100

We divide both sides both sides by 2 to get,

x = 50

x + y = 50 + 10

x + y = 60


Method 2

Angles on straight line sums to 180°.



2y-5+85=180


This implies that,

2y+80=180


2y=180-80


2y=100


y=50



Also,


3x+55+95=180


3x+150=180


3x=180-150


3x=30


x=10


x+y=50+10


x+y=60

Solve the equation for y.<br> 8x – 9y = 11
pav-90 [236]
8x-9y=11

First you move the 8x because you have to leave the 9y alone

8x-9y=11
-8x        -8x

-9y=11-8x

Now you have to move the -9, so the inverse of multiplying is dividing so you divide -9.

-9y/-9= 11/-9 -8x/-9

since you can't have negative as a denominator it would be:

y= -11/9+8x/9

As the angle θ increases to 90° the value of tan(θ)
Nutka1998 [239]

Answer:

C. increases rapidly.

Step-by-step explanation:

tan(θ) =  sin(θ)/cos(θ)

Now, when sin 90 = 1

and cos 90 = 0

so, tan(90) = 1/0 = not defined.

<em>(1/0 is infinity and its value is not defined)</em>

So, when angle θ increases to 90°, then the value of tan(θ) increases rapidly, as shown in the figure below.
