Can someone me and explain cause i’m really confused

60 (C).

Step-by-step explanation:

FIrst off, the part that's most likely confusing you is the exponents and parenthesis. The exponents, if outside the parenthesis, affect everything inside the parenthesis. If the exponents are inside the parenthesis, however, they only affect the numebr they are attached to.

5+4 = 9, so 9^2 - (5 + 4^2).

4^2 = 16.

9^2 = 81.

81 - (5 + 16) = 81 - 21.

81 - 21 = 60.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
