Answer:
x=0
Step-by-step explanation:
-2(2(5x - 9) -3 (2x + 5))
-2 (10x - 18 - 3 (2x + 5))
-2 (4x -18 -15
Answer = -2(4x - 33)
The complement of 45° is the angle that when added to 45° forms a right angle(90°) 90°-45 =45
First, 45 is the total number of students. So you have to add the ratio: 2+3=5. Since you are finding the number of sixth graders, you need to use the ratio 2.
Sixth graders : All = x : 45
2 : 5 = x : 45
You could change this to fractions and solve it.
2/5 = x/45
x = 18
So there are 18 sixth graders.
Answer:
Step-by-step explanation:
Formula for any given angle (Ѳ) is given as csc Ѳ = length of hypotenuse side//length of opposite side. It is the inverse of sin Ѳ.
In the right triangle given above, the opposite length = 24, while the length of the hypotenuse = 26
Thus,
