Plz help meh, it is about mathamatics

D

Step-by-step explanation:

This is actually a really easy question. I have three ways to solve this:

1) 180- (54+64)=62, 180-62=118, like the solution

2. Since 54+64+c=180 and 180-c= d, d=54+64, which equals 118.

3. Deduction! d is not a straight line, cannot be more than 180 degrees, and can't be smaller than 90 degrees, so halfway through solving by 1), you've already got the answer!

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
