Question 1) x=4
the rest I rly dk
Answer:
x=9
y=
Step-by-step explanation:
This is a special type of triangle known as a 45-45-90 triangle.
The ratio for the sides of this triangle are x:x:x
Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.
The hypotenuse, however, is the value of one side multiplied by
.
In this case it is 9, so 9*
= 
The two expressions could be :
2 - 1/2m
2 - m / 2
I’m not for sure of the answer but i do know that the two subtractions in the middle would turn into a + and i think you add the -5/8 + 3/10
