Step-by-step explanation:

23. area of rect,r = 11 x 3.5 = 38.5cmsq

area of tri, t = 6 x3.5/2 = 10.5 cmsq

area of shaded region, sr = r-t

=> sr = 38.5- 10.5 = 28.5cmsq

24. area of square, s = 10x10 = 100mmsq

area of circle, c = pi x 5^2 = 78.5mmsq

area of shaded region, sr = s - c

=> sr = 100- 78.5 = 22.5mmsq

25. area of circle, c = pi x 6^2 = 113.04insq

area of tri, t = 6x12/2 = 36insq

area of shaded region, sr = c - t

=> sr = 113.04 - 36 = 77.04insq

<h3>How to compute the value?</h3>

From the information, the candidates running for office are handing out items to voters as every 6th voter gets a button while every 7th voter gets a sticker.

Therefore, it should be noted that the least common multiple of both 6 and 7 is 42. Therefore, the voter is the first to receive both items is the 42nd voter.

Answer:

D

Step-by-step explanation:

A triangle is always determined by the names of its angles. If, for any reason, you wanted to label it by its side names(which I don't even think you can do but assuming you wanted to), you dont even have the names for all three sides here. So, it can only be d. A, X, and T are the three angle names for this triangle, so this is triangle ATX or AXT.
