Can anybody help me find out how to get the other marks on this question please?

the percentage is 55/100*100=55%

Step-by-step explanation:

the segment of the square is 40/4=10 cm

so the area of the square is  10^2=100cm^2

the shaded area = the  area of the square -  the sum of the areas of  the triangles inside the square

100- (10*6/2+10*3/2)=100-(30+15)=55 cm^2

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
