Answer:
59.04
Step-by-step explanation:
If you were to make a right triangle, 15 would be the altitude (height), and 9 would be the base. You need the angle of elevation which is going the angle of the hypotenuse going upwards. (Bottom Left/Right Corner.) From that angle you need to solve for arctan (Used for solving the measure of angle.) Simply plug into your calculator arctan(15/9) to get the answer.
P = 2l + 2w
P = 2(x + 3) + 2(7)
P = 2(x) + 2(3) + 14
P = 2x + 6 + 14
P = 2x + 20
A = lw
A= 7(x + 3)
A = 7(x) + 7(3)
A = 7x + 21
3/5+1/2=6/10+5/10=11/10
hope this helps!
Answer:
5x-4=11
Step-by-step explanation:
so you multiply 5 times x (a number) and subtract 4 and it equals to 11
Answer:
5/12
Step-by-step explanation:
to divide fractions you find the reciprocal of the 2nd number
and times both of the numbers
1/3 times 5/4
Multiply numerator and denominator.
=5/12
