The 3 inside angles of a triangle need to equal 180

you have 80 +60 = 140

so 51+x has to equal 180-140 or 40 degrees

51+x = 40

subtract 51 from each side
x = 40 - 51
x = -11

Just add up all 60 + 80 + 51 = 191.

191 - (-11) = 180 which is the number we would want to get.

(-11) would then because your answer as we do 180 + (-11) it would equal the sum of 191 which would be all the angles together.

Your answer: = (-11)

What is third of 1 5/8
stiv31 [10]

1 5/8 = 13/
8
= 1 5/
8
= 1.625
Spelled result in words is thirteen eighths (or one and five eighths).

How do you solve fractions step by step?
Conversion a mixed number 1 5/
8
to a improper fraction: 1 5/8 = 1 5/
8
= 1 · 8 + 5/
8
= 8 + 5/
8
= 13/
8


To find new numerator:
a) Multiply the whole number 1 by the denominator 8. Whole number 1 equally 1 * 8/
8
= 8/
8

b) Add the answer from previous step 8 to the numerator 5. New numerator is 8 + 5 = 13
c) Write a previous answer (new numerator 13) over the denominator 8.

One and five eighths is thirteen eighths

Solve the following problem, round your answer to the nearest 2 decimal places if needed.

Applying the midsegment theorem, the <u>value of x = 5</u>

<em><u>Recall:</u></em>

  • The midsegment theorem of a triangle states that the length of the mid-segment (DE) which is parallel to the third side (AC), is half the length of the third side AC of triangle BAC.

<em><u>Thus:</u></em>

DE = 1/2(AC)

  • Substitute

2x - 3 = 1/2(x + 9)

  • Multiply both sides by 2

2(2x - 3) = x + 9

4x - 6 = x + 9

  • Combine like terms

4x - x = 6 + 9

3x = 15

  • Divide both sides by 3

x = 5

Therefore, applying the midsegment theorem, the <u>value of x = 5</u>

<u></u>
