What is the value of X in this?

Answer: 52°

Step-by-step explanation: In this problem, we're asked to use the diagram shown to find the value of <em>x</em>.

Since the two lines in the figure intersect,  we know that they form vertical angles and remember that vertical angles are congruent.

Since our diagram tells us that one angle measures (x + 35)° and the measure of the other angle is (3x + 1)° and we know that these angle measures are equal, we can setup the equation x + 35 = 3x + 1.

Solving from here, we subtract x from both sides to get 35 =2x + 1

and subtracting 1 from both sides we have 34 = 2x.

Now dividing both sides by 2, we find that 17 = x.

Now, we plug a 17 back into one of our angles.

So let's do (x + 35)°

Plugging in a 17, we have (17) + 35 or 52°.

Answer:

x=17

Step-by-step explanation:

The vertical angle theorem states that these two angles are congruent.

So,

x+35=3x+1

35-1=3x-x

34=2x

x=17

PLSSS HELP I AM BEGGING!!! For each triangle, find the measure of the missing angle.
IgorC [24]

so all angles of a triangle are going to add up to 180°

<u>so for L</u>

20 + 72 + x = 180

92 + x = 180

180 - 92 = 88

<u>For I</u>

56 + 89 + x = 180

180 - 145 = 35

<u>For C</u>

28 + 128 + x = 180

180 - 156 = 24

<u>For D</u>

122 + 38 + x = 180

180 - 160 = 20

Help plz <br> How do you solve
tensa zangetsu [6.8K]

Answer:

y=4\sqrt{3}\ units

Step-by-step explanation:

Triangle MRN is created by folding an equilateral triangle by half. Since triangle MRN is right triangle, the equilateral triangle must be folded along the height drawn to one side.

In equilateral triangle with side length of a units, the height is \dfrac{a\sqrt{3}}{2}\ units and the height is greater than half the side because

\dfrac{a\sqrt{3}}{2}>\dfrac{a}{2}.

The leg with length x units has the smaller projection (2 units long) than the leg with length y units has (6 units long).

This means the leg with length y units is the height of the equilateral triangle. If the leg with length y units is the height of the equilateral triangle, then the hypotenuse MN = 8 units is the side of the equilateral triangle and lex with length x units is half the side, so x = 4 units.

By the Pythagorean theorem,

y^2=8^2-4^2\\ \\y^2=64-16\\ \\y^2=48\\ \\y=4\sqrt{3}\ units

The standard deviation for a set of data is 9.5. The mean is 205.
Anon25 [30]

If the standard deviation for a set of data is 9.5. The margin of error is: 19.5.

<h3>Margin of error</h3>

Using this formula

Margin of error=Standard deviation×Mean

Let plug in the formula

Margin of error=205 × 9.5%

Margin of error = 19.475

Margin of error = 19.5 (Approximately)

Therefore If the standard deviation for a set of data is 9.5. The margin of error is: 19.5.

Eduardo puts $40 into his piggy bank and plans to add $5 each month. Write an equation to represent this.​
igomit [66]

Answer:

40+5x

Step-by-step explanation:

Eduardo put $40 in so the 40 is what he has already put in. Next you have $5 added in but it doesn’t say for how many months just that it’s each month so we put the x to represent out unknown so we can solve the equation.
