Answer:

∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°

Step-by-step explanation:

<h3>Solving for x</h3>

We can say that angle ABC and angle DBE are vertically opposite angles because there are only two intersecting lines. Vertically opposite angles are equal so we can form an equation:

4x + 2 = 5x - 13

5x - 4x = 2 + 13

x = 15

<h3>Angles ABC and DBE</h3>

Now we can substitute x into the equation and find out the value for angles ABC and DBE.

4(15) + 2 = 60 + 2 = 62°, just to make sure we need to substitute x into the other equation to see whether we get the same answer:

5(15) - 13 = 75 - 13 = 62°, now we can confirm that angles ABC and DBE are 62°.

<h3>Angles CBE and ABD</h3>

Now we can use the rule, angles on a straight line add up to 180°, to find the other two angles, because these two angles are vertically opposite, they are also equal to each other.

180 - 62 = 118°

Angles CBE and ABD are both 118°

The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27

put x into angle B,we have
2(27)-1
=53

thus angleB is 53°

hope it helps c:

-5x-12&gt;6x-4 Solve the inequality and give the answer in interval notation.
lora16 [44]

-5x-12>6x-4

To Solve the inequality we need to get x alone

-5x-12>6x-4

first we remove -12, for that we add 12 on both sides

-5x-12+12>6x-4+12

-5x > 6x +8

Now subtract 6x from both sides

-5x -6x> 6x-6x +8

-11x > 8

Divide by -11. when we divide by -11 we flip the inequality . so > becomes <

x < -\frac{8}{11}

We need to give the answer in interval notation.

x is less than -8/11 so x value starts from -8/1  and goes to -infinity(left)

So interval notation is (-∞, -\frac{8}{11})
