Hey there mate ;), I'm Benjemin.

Nice to meet you.

Now let's solve your question :)

<u>Step</u><u> </u><u>1</u><u>:</u><u>-</u> Re-draw the triangle. Check the attached first image.

<u>Step</u><u> </u><u>2:-</u> Considering the triangle ABC, it can be seen that the triangle is isosceles. This means that angles ABC and ACB are equal. To get the value of X,

110 + x + x = 180 \\  =  > 110 + 2x = 180 \\  =  > 2x = 108 - 110 \\   =  > 2x = 70 \\  =  > x =  \frac{70}{2} \\  =  > x = 35

<u>Step</u><u> </u><u>3</u><u>:</u><u>-</u> Draw another part of the picture to find the other X, for it, check second attached image.

To get BCD, Using alternate angles theorem,

ABC = BCD <em>(Alternate angles are equal)</em>

<em>=</em><em>></em><em> </em><em> </em>ABC = 35°

=> x = BCD = 35°

Therefore, value of x is <u>35°</u> and 2X=2×35=<u>70°</u>

Triangle ABC and Triangle DEF are similar. For triangle ABC, AB = 2x , AC = 24 inches and BC = 20. For triangle DEF, EF = 5 and
Norma-Jean [14]
X=8.

Following the similarity statement, we know that AC is to DF as BC is to EF.  The ratio would be:

24/(x-2) = 20/5

Cross multiply:
24*5 = 20(x-2)

Use the distributive property:
120 = 20x - 40

Add 40 to both sides:
120+40 = 20x - 40 + 40
160 = 20x

Divide both sides by 20:
160/20 = 20x/20
8 = x

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
