Answer:
Step-by-step explanation:
The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.
find the value of x
x + 2x + x + 8 = 180
4x = 180 - 8
4x = 172
x = 172 : 4
x = 43
find angles
2x = 43 * 2
2x = 86°
-------
x = 43°
--------
x + 8 = 43 + 8
x = 51°
-----------------------
check
86 + 43 + 51 = 180°
the answer is good
Answer:
En la expresión, 2 representa la cantidad de veces que multiplicas x por sí mismo.

Step-by-step explanation:
= 8 × 8 = 64
= y × y
Add or subtract 360 degrees to find a coterminous angle. Since the questions wants you to find one between 0-360, you should subtract 360.
453-360=93 degrees
Answer:

Step-by-step explanation:
You are going to integrate the following function:
(1)
furthermore, you know that:

lets call to this integral, the integral Io.
for a general form of I you have In:

furthermore you use the fact that:

by using this last expression in an iterative way you obtain the following:
(2)
with n=2s a even number
for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:
