75
Step-by-step explanation:
after adding all the measures the sum give around 75, don't forget to add 11 ¾ in the left side
Answer:
43°
Step-by-step explanation:
In a isosceles triangle, two angles HAVE to be equal.
This means that 94 can be one of the angles that are equal, or the angle that is not equal to another angle.
Let's start with the fact that 94 can be one of the angles that are equal. (Note: angles in a triangle add up to 180)
94+94+x=180
188+x=180
There is NOT a possible value for x in this situation, as you cannot have a negative value of an angle. Therefore we must try the other situation where 94 is the angle that is not equal to another angle.
x+x+94=180
2x+94=180
Subtract 94 from both sides
2x=86
Divide both sides by 2
x=43
Therefore the answer is 43°
Answer:
(x + 0.5) (x² - 0.5x + 0.25)
Step-by-step explanation:
x³ + 1/8
We can rewrite 1/8 as a decimal: 0.125
the cubed root of 0.125 then is 0.5; recalling that 5³ yields 125
Knowing this then, we can factor out our expression
(ax + b) (ax² − abx + b² ) = ax³ + b³, where a and b are coefficients.
If a = 1, and b we found to = 0.5, our expression becomes
(x + 0.5) (x² - 0.5x + 0.25)
We cannot further factor x² - 0.5x + 0.25, so our answer remains
(x + 0.5) (x² - 0.5x + 0.25)
Check via foiling
(x * x²) + (x * -0.5x) + (x * 0.25) + (0.5 * x²) + (0.5 * -0.5x) + (0.5 * 0.25)
x³ - 0.5x² + 0.25x + 0.5x² - 0.25x + 0.125 Combine like terms
x³ + 0.125 = x³ + 1/8
68 is the answer of the question you ask the committee
