Hello,
45° since a tangentiel angle is the half of the angle in the center corresponding.
Answer:
x(θ) = 5 tan θ
Step-by-step explanation:
Given that:

we are to state the trigonometric substitution to be used to find the indefinite integral.
Suppose u is the variable and a is the constant
u = x
a = 5
So; (a² + x²)ⁿ
which is a trigonometric substitution for x = a tanθ
Then,
x(θ) = 5 tan θ
You should write a 1 because I f what you add is 11, 12, 13, 14, 15, 16, 17, 18, or 19 there is a 1 in the front of the numbers so you must put a 1 but if the number was 76 the number in the front is 7 so you would put 7 on the tens column.
Answer. First option: -1
Solution:
We have a triangle, and we know two angles of 60° each one. We can find the third angle A, using:
A+B+C=180°, with B=60° and C=60°:
A+60°+60°=180°
Solving for A: Adding similar terms:
A+120°=180°
Subtracting 120° both sides of the equation:
A+120°-120°=180°-120°
A=60°
The third angle A is 60° too, then the triangle has three equal angles of 60° each one, and it is an equillateral triangle, thus its three sides must be congruents:
2y+6=4=2x-3
We need to find the value of y, then using the first equality:
2y+6=4
Solving for y: Subtracting 6 both sides of the equation:
2y+6-6=4-6
2y=-2
Diniding both sides of the equation by 2:
2y/2=-2/2
y=-1
