Answer:

A) (2x+15)=65=180°

Step-by-step explanation:

Hey there!

It's a straight line, which means that the sum will be 180°.

So, (2x+15)=65=180°

Hope this helps!

Answer:

Step-by-step explanation:

These angles are supplementary (or a linear pair), meaning they add up to 180 degrees. We can use this information to set up an equation...

(2x+15)+65=180

Therefore the answer is A

Plz answer!! thanks

Answer:

x = 10

y = 40

Step-by-step explanation:

60° + (2x + 7y)° = 180° because these two angles are supplementary

So 2x + y would be equal to 60°

60° + (2x + 7y)° = 180° subtract 60 from both sides

2x + 7y = 120 and

2x + y = 60 multiply second equation by -1 and it will be -2x -y = -60 now add it to first equation

2x + 7y -2x - y = 120 - 60 -2x will eliminate 2x

6y = 60 divide both sides by 6

x = 10

if 2x + y = 60 the we need to replace x with the value we found

2×10 + y = 60

y = 40

Answer:

Part a .............> x = 11

Part b .............> k = 57.2

Part c .............> y = 9.2

Explanation:

The three problems deal with inverse variation between two variables

An inverse variation relation between two variables means that when one of the variables increases, the other will decrease (and vice versa)

Mathematically, an inverse variation relation is represented as follows:

$y = \frac{k}{x}$

where x and y are the two variables and k is the constant of variation

Now, let's check the givens:

Part a:

We are given that y = 3 and k = 33

Substitute in the original relation and solve for x as follows:

$y = \frac{k}{x}\\ \\3 = \frac{33}{x}\\ \\x=\frac{33}{3}=11$

Part b:

We are given that y = 11 and x = 5.2

Substitute in the original relation and solve for k as follows:

$y=\frac{k}{x}\\ \\11=\frac{k}{5.2}\\ \\k=11*5.2=57.2$

Part c:

We are given that x=7.8 and k=72

Substitute in the original relation and solve for y as follows:

$y=\frac{k}{x}=\frac{72}{7.8}=9.2$ to the nearest tenth

Hope this helps :)
