Answer:

x = 20

Step-by-step explanation:

The small square at the vertex indicates a 90º angle

Therefor

x + (3x + 10) = 90

Combine like terms

4x + 10 = 90

Subtract 10 from both sides

4x = 80

Divide both sides by 4

x = 20

Which integer is closest to 0 on the number line?
IrinaVladis [17]

An integer is close to zero if it is "small".

By small, we mean that it is small in absolute value. In fact, for any given distance d, there are two integers that are d units away from zero: d and -d.

So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.

So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.

Please help me<br> Solve for x.<br> a) 30<br> b) 27<br> c) 33
OlgaM077 [116]

Answer:

x = 27

Step-by-step explanation:

The angle at any point on a straight line is 180 degrees.

The middle line over there is creating a right angle which is 90 degrees.

This must mean that both sides are 90 degrees.

3x+9 = 90

3x = 81

x = 27

Geometry question please help will give Brainlyest!<br><br> I need the x, y, and z please.
kozerog [31]

Answer:

x=24

y=10

z=17

Step-by-step explanation:

These triangles are congruent, which means that the corresponding angles are equal to each other.

Let's start with <em>x</em>. Angle H corresponds to angle N, so we set them equal to each other and slove.

x=24

Next, let's look at z. Angle C corresponds to angle P, so again we set them equal. Z=17.

Finally, we must find y. F and S correspond, but we don't know what the measure of angle S is, but we do know that the interior angles of a triangle add up to 180 degrees, so we solve for angle S and get 115°.

180-(36+115)=29

We now know that angle F equals 29. From solving, we know that Y=10.
