Answer:
See below.
Step-by-step explanation:
Gertrude is correct. Any angle can have one line of symmetry going directly down the center of the angle, intercepting at the angles point. Emmet is incorrect because not only polygons can have lines of symmetry. A circle, square, rhombus, etc. can have lines of symmetry.
Answer:
200
Step-by-step explanation:
i did a little bit of guessing and checking but the answer is 200 because if you multiply 200 by 1 it comes out to 200 and if you multiply it by .26 it comes out to 52. you multiply by .26 because it was 26% and you need to move the decimal over 2 when changing to decimal form. to find it immediately, you multiply 200 by 1.26 and it comes out to be 252 (sorry about the sloppy handwriting)
The answer is c and the rest of what I’m saying is nonsense bc I need to use more characters lol
Answer:
x = 17
Step-by-step explanation:
The two angles form a right angle ( indicated by the square )
Right angles have a measure of 90°
Thus, x + 73 = 90
90 - 73 = 17
Hence, x = 17
Answer: The three consecutive even numbers are <u>22, 24, 26</u>
22+24+26 = 72
========================================================
Explanation:
- x = first even number
- x+2 = second even number directly right after x
- (x+2)+2 = x+4 = third even number directly after x+2
For example, if x = 12, then we'd have x+2 = 12+2 = 14 and x+4 = 14+4 = 18.
However 12+14+18 = 44 is not 72 like we want.
You can guess-and-check your way to the answer, but a faster efficient route is to use algebra. Add up those x expressions and set the sum equal to 72 and solve.
(first) + (second) + (third) = 72
(x) + (x+2) + (x+4) = 72
3x+6 = 72
3x = 72-6
3x = 66
x = 66/3
x = 22
So we have,
- x = 22 = first even number
- x+2 = 22+2 = 24 = second even number
- x+4 = 22+4 = 26 = third even number
As a check: 22+24+26 = 72 which verifies the answers.
