X = 10
the two sides are congruent and you know that by finding the other angle 90+45= 135
180-135=45
y= 14.1
10^2+10^2=c^2
100+100=c^2
200=c^2
14.142.. =c
Answer:
We have to determine the graph of the given inequality as:
on solving this equation we get:
Since we know that:
Now we know that when 
the value of:
Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.
Hence, range of the function in intervals could be written as:
(-∞,-1)∪(-1,∞).
Hence, the graph of the function will be the whole of the number line with a open circle on -1.
Answer:
4 m
Step-by-step explanation:
The geometry is that of a right triangle with hypotenuse 8.5 m and one side of length 7.5 m. If "b" represents the distance from the base of the ladder to the wall, the Pythagorean theorem tells us ...
b² + 7.5² = 8.5²
b² + 56.25 = 72.25
b² = 16 . . . . . . . . . . . . . subtract 56.25
b = 4 . . . . meters . . . (take the square root)
The base of the ladder is 4 m from the wall.
_____
You may recognize this as the 8-15-17 Pythagorean triple, scaled by 1/2.
4-z+10=1
+4
-z+14=1
-14-14
-z=-13
Z=13
42:35 or if simplified 6:5
