Answer:
x=-8
Step-by-step explanation:
2x+2=-14
2x=-16
x=-8
The given angles are =
(x+40)° and 3x°
As the given angles are opposite to each other on the intersecting lines, so they are vertical angles. These are congruent or equal.
So, 


Hence x = 20°
The given angles are =
(x+40) = 20+40 =60°
3x = 3*20 =60°

Answer:

Step-by-step explanation:
For this case we want to find this probability:

Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:

The other possibility is use the normal standard table and we got a similar result.
Answer:
Its an Isosceles triangle. The two bases are equal
So
x= 180-(62+62)
x=56°.
