Answer: 30 degrees
Step-by-step explanation:
Corresponding angles of similar triangles are congruent.
For D:
A triangle always has 180 degrees total. No more, no less. Seeing as though all the sides and angles are the same length, we can just divide 180 by 3, giving us 60. x = 60 degrees.
For E:
We can see there is a 90 degree symbol that surmises both angles. We know the lower angle is 30 degrees, so m must equal 60 degrees.
For G:
Same concept as D, except we gotta do a bit of math. A triangle always has 180 degrees, So we add 50 and 55 together and get 105. Subtract 105 from 180 and we get 75. Therefore, your angle is 75 degrees.
For H:
The 75 degree angle and m are parallel, with the same line passing through it, meaning that m is identical to the other angle. m = 75.
Answer:
-15
Step-by-step explanation:
10x-3y= -15
Remember, there is a missing term which is crucial to solving this, and that is 0x.
Ima use synthetic division, because that's the quicker option here:
The zero of x+2 is -2...
-2 | 3 5 1 0 -5
-6 2 -6 12
_____________
3 -1 3 -6 7
(Sorry, I'm unsure how to fix the formatting, plus I'm new to this. The -6 and such on the second line should be below the 5 and following of the first line, and the 3 and such on the last line should be below the 3 and following on the first line, leaving a space between the 3 on the first and third line.)
So the answer is: A. 3x^3 - x^2 + 3x - 6 + 7/(x+2)
