What is the value for x and for y?

What Is The Value For X And For Y?

Answers

Answer 1

Answer:

20+7x=90

x=10

50+2y=90

y=20

Answer 2
I think
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

What is an angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

We have been given a diagram in which point B is the midpoint of line ABC. We are asked to choose the correct statements about our given diagram.

A. DBC is bisected by ray BD.

Since DBC is an angle for our given diagram and side BD is terminal side of angle DBC, therefore, option A is false.

B. ABC is bisected by ray BD.

We have been given that point B is the midpoint of segment ABC, this means that ray BD bisect line ABC. Therefore, option B is true.

C.

Since point B is midpoint of line ABC, so AB will be equal to BC.

i.e. we get,

BC = AC/2

Therefore, option C is the correct choice.

D. 2mDBC = mABC

We can see that measure of angle DBC is 90 degrees.

We can see that ABC is a line and measure of linear angle is 180 degrees,

therefore,  and option D is true.

62.5% as a decimal and as a fraction. PLEASE SHOW WORK.

Answers

Answer:

62.5 as a decimal would be 0.625

As a fraction it would be 625/1000.

Step-by-step explanation:

To write 0.625 as a fraction you have to write 0.625 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.625 = 0.625/1 = 6.25/10 = 62.5/100 = 625/1000  

And finally we have:

0.625 as a fraction equals 625/1000

Answer:

⇒62.5÷100
