Answer: (8, -13)
Step-by-step explanation:
-2 is 5 away from 3, and 9 is 11 away from -2. so add 5 to 3 which is 8, and add -11 to -2 which is -13.
5+3=8 (x)
-11+(-2)=-13 (y)
There for the correct answer is (8, -13) when (x, y).

Answer:
x = 30.91 cm , y = 29,86 cm and z = 39.30 cm.
Total area of wood = 2942.54 cm^2.
Step-by-step explanation:
sin 15 =8/x
x = 8 / sin 15
x = 30.91 cm.
and
tan 15 = 8/y
y = 8 / tan 15
= 29.86 cm.
The value of z can be found using the Pythagoras theorem:
50^2 = x^2 + z^2
z^2 = 20^2 - x^2 = 50^2 - 30.91^2
z^2 = 1554.57
z = √1554.57
= 39.30 cm.
b. The area consists of 3 rectangles :- 1. sides x and z 2. sides z and 8 and the other has sides z and y. Also 2 triangles of height 8 and base length y cm.
Total area = 30.91 * 39.30 + 8 * 39.30 + 29.86 * 39.30 + 2 * 0.5 * 8 * 29.86
= 2942.54 cm^2.

Answer:
No solution
Step-by-step explanation:
3(x-3)+5=3x+1+4
3(x-3)+5=3x+5
3x-9+5=3x+5
3x-4=3x+5
+4 +4
3x=3x+9
-3x -3x
0≠9
Hope this helps!
