Solve for x going step by step .

Mathematics
1 answer:
OleMash [197]3 years ago

Answer:

x=11

Step-by-step explanation:

We know that  the angle is equal to 1/2 the difference of the long arc length between where the line segments touch the circle and the small  arc length where the line segments touch the circle

They long distance is 360 - (86+74) = 200

The small distance is 86

4x+13 = 1/2 ( 200  - 86)

4x+13 = 1/2 (114)

4x+13 = 57

Subtract 13 from each side

4x+13-13 = 57-13

4x= 44

Divide by 4

4x/4 = 44/4

x=11

Sovle the following inequality -3m + 18 < 30​
denis-greek [22]

Answer:

m>-4

Step-by-step explanation: First subtract 18 from both sides, then simplify 30-18, which equals 12. Divide both sides by -3, and flip your sign.

Help me with this plsss 40 pointsss
lara [203]

Answer:

Step-by-step explanation:

x(3x+2)=16

3x²+2x-16=0

3x²+8x-6x-16=0

x(3x+8)-2(3x+8)=0

(3x+8)(x-2)=0

either 3x+8=0

x=-8/3(rejected as width can't be negative)

x-2=0

x=2

so width=2

length=3×2+2=6+2=8

Solve for n <br><br> 11/6=n+7/9<br><br><br> (Plz no trolling; will mark brainiest)
xxTIMURxx [149]

Answer:

n=\frac{19}{18}

Step-by-step explanation:

Ir order to find the value of n in the given linear equation: \frac{11}{6} = n + \frac{7}{9} you have to perform the properties of equalities to obtain an equivalent equation.

You have to perform these properties in each side of the equation.

Applying the subtraction property (which is the subtraction of the same number to each side of the equation):

Adding \frac{7}{9} to each side:

\frac{11}{6} - \frac{7}{9} = n + \frac{7}{9} - \frac{7}{9}

This way you can obtain the value of n

\frac{11}{6} - \frac{7}{9} = n

Solving the subtraction of the fractions and simplifying:

\frac{(11)(9)-(7)(6)}{(6)(9)} = n\\\frac{57}{54} = n\\n=\frac{19}{18}

Which of the following verifies that AABC is similar to A DEF?
emmainna [20.7K]

Answer:

D

Step-by-step explanation:

According to the SAS theorem, if the 2 sides of the 2 triangles are multiples of each other by the same scale factor, with the angle in between them being the same for each triangle. The triangles are similar.

The SSS theorem is not appropriate here because we do not know the side lengths of AB or DE in the diagram. For SSS theorem we need to know all of the side lengths.

A is incorrect because the similarity can be determined.
