Answer:
Circular!
Step-by-step explanation:
Triangle ABC is reflected across the y-axis to form the image A'B'C'. Triangle A'B'C' is then reflected across the x-axis to form the image A''B''C''. What type of rotation can be used to describe the relationship between triangle A"B"C" and triangle ABC
AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
Answer:
C. 342
Step-by-step explanation:
This year, 150% of last year's tickets were sold.
Last year, 228 tickets were sold.
150% as a fraction is 150/100
To find the amount of tickets sold this year, we take the 150/100 and multiply it by 228:
150/100*228= 342 tickets
Answer:
veinte
Step-by-step explanation:
Son veinte porque si alineas 10 + 10 así-
10
+ 10, solo agregas las que serán un dos. Luego sueltas el cero, que será 20.
Answer:
A = 5x + 12 (See explanation!)
Step-by-step explanation:
So, this "polygon" is really just two rectangles combined! With that in mind, remember that the area of a rectangle is base*height. Now, apply that to the problem. We know that the total length of the bottom base is 7, and 5 is the length of the second rectangle's base, so the 1st rectangle's base must be 7 - 5 = 2. The area of the 1st rectangle is then 6*2 = 12. The second rectangle's area is 5*x. So, if the area of the polygon is the sum of the two rectangles' areas, the expression you could use is:
5*x + 6* 2 = A
Simplify/Rewrite:
A = 5x + 12
(A is area, x is the unknown length in the diagram)
Hope this helps!
