The sum of adjacent angles on a straight line would be 180°.

Since x is on a straight line,what we need to do is to deduct the remaining two angles,here's what the equation would be like:

180°-90°-30°
=60°

Thus,x=60°

hope it helps!

Hello!

The angle is a straight angle, which measures 180°.

One angle is a right angle, which measures 90°, while the other angle measures 30°.

90 + 30 = 120

That means x = 180 - 120. To find x, subtract 120 from 180

180 - 120 = 60

 \framebox{x = 60 \°}

A square has a side length of 5 and 1/4 inches what is the area of a square
padilas [110]
Answer: 27.5625 or 27.6

Explanation:
A square has even side lengths so each side equals 5 1/4 or 5.25. So you take two sides and multiply them together. In other words, 5.25•5.25. Then you get roughly 27.6 rounded

What would (4,3) be after it is reflected to the y=x
Paul [167]

Answer:

(3,4)

Step-by-step explanation:

The amount of steps applied from the reflection line to the point would be also applied inversely to the image point (after reflection).

From y=x to (4,3), it goes 1 down and also goes 1 right. (NOTE: It does not go down and right. Instead, it goes <em>either</em> down and right)

So now inverse that to make 1 up and also going 1 left.

romeo makes $12.00 an hour for his first hour of work, $17.00 his second hour, $22.00 his third hour and so on. How much money i
vaieri [72.5K]

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257

Ach equation:<br> - 5(– 2x - 4) + 5x - 4 =- 29
Zinaida [17]

- Multiply (-2x-4) by -5:

[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29

= 10x+20+5x-4=-29

- Combine Like Terms:

(10x+5x) + (20-4) = -29

15x+16=-29

- Subtract 16 from each side

15x+16 -16 = -29 -16

15x = -45

x = -3

The bear lake is 24 miles long. Suppose John starts cycling art one end at 20 m.p.h. and Ramona starts at the other end at 15 m.
Fed [463]

Answer:

24/35 hours  or 0.69 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x-----> distance traveled by John

(24-x) ----> distance traveled by Ramona

The time is equal to divide the distance by the speed

so

x/20=(24-x)/15

15x=20(24-x)

15x=480-20x

15x+20x=480

35x=480

x=480/35 miles

the time is equal to

t=x/20

t=480/(20*35)=24/35=0.69 hours
