Answer:
3. X = 13.42
Step-by-step explanation:
12² + x² = 18²
144 + x² = 324
-144 -144
x² = 180
√x² = √180
x = 13.41640 (unsure of how teacher would want you to round this, probably in the hundredths)
x = 13.42
Answer:
x = 45
y = 45
z = 11.1
Step-by-step explanation:
Remark
The triangle is a right triangle. That means that it has 1 right angle.
It is also isosceles which means that the two legs that are not the hypotenuse are equal.
Result: z and 11.1 are equal z = 11.1
More remark
If the triangle is isosceles, that means that the angles that are not right angles must also be equal.
90 + x + y = 180
but x = y
90 + 2x = 180 Subtract 90
2x = 180 - 90 Divide by 2
2x/2 = 90/2
x = 45
(2,6) it’s where they cross. If there isn’t a graph make the two equations equal to each other to find x then plug in x to either equation to find y
I do believe that it is the second one I’m not 100% sure but I’m pretty sure it is
