The answer is 35.84.
You just add all of them up
X is bigger than 65 but smaller or equal to 69. Looks a bit like this...6569.
(However “>“ is a little different as there should be a line under it to show how it can be equal to 69.
Answer:
Step-by-step explanation:
X>X
-4+X>-2+X
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Answer:
4x - 4y - 7z
Step-by-step explanation:
x - 3y + 4z + y - 2x - 8z + 5x - 2y - 3z =
(x - 2x + 5x) + (y - 3y - 2y) + (4z - 8z - 3z) =
4x + (- 4y) + (-7z) =
4x - 4y - 7z <===
