Answer:
Step-by-step explanation:
This triangle is a 45-45-90 triangle.
By using the image I posted, we can find x easily.
So, we have 
as one of the sides.
They hypotenuse, which is x is just 
Simplify and we get x = 
Answer: the answer is a
Step-by-step explanation: if you look at the choices they give you it’s would help you see if they look alike
i hope this helps :)
The answer is the third answer because it is the only option where the number 45 is multiplied by something bigger than 1. If something is multiplied by something smaller than one then it will be smaller than the number multiplied.
Aka: 45x0.8 is 36, because 0.8 is smaller than one
Answer:
x = 85°
Step-by-step explanation:
As noticed this is a Pentagon (5 sided polygon); therefore to find x, first we have to find the sum of it's interior angles;
Sum of interior angles of a pentagon = (n - 2) * 180°
=> Sum of interior angles of a pentagon = (5 - 2) * 180°
=> Sum of interior angles of a pentagon = 3 * 180
=> Sum of interior angles of a pentagon = 540
Now that we know the sum of interior angles, we can set up the equation and solve for x;
115 + 95 + 115 + 130 + x = 540
455 + x = 540
x = 540 - 455
x = 85
Hope this helps!
