Construction of the angle pi/6=30 degrees produces a 30-60-90 triangle, which has angles theta=pi/6 and 2theta=pi/3.
Step-by-step explanation:
Answer: 70 meters
Step-by-step explanation:
Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.
Replacing with the values given:
65^2 = 16^2 + x^2
4,225 = 256 + x^2
4,225-256 = x^2
3,969=x^2
√3,969 =x
63=x
We have calculated the missing side of the triangle, now we have to add the height of the rectangle:
63 +7 =70 meters

Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such
