Answer:
1. (5x - 2) + (2x - 2) + x = 
2. m<J = 
3. m<K = 
4. m<L = 
Step-by-step explanation:
Generally, the sum of angles in a triangle =
.
So that;
m<J + m<K + m<L = 
(5x - 2) + (2x - 2) + x = 
5x + 2x + x -2 -2 = 
8x - 4 = 
8x =
+ 4
8x = 184
x = 
x = 
Thus,
m<J = (5x - 2)
= 5(23) - 2
= 
m<K = (2x -2)
= 2(23) - 2
= 
m<L = x
= 
Answer:
x^2 -2x + 1
Step-by-step explanation:
Think of a quadratic equation as
ax^2 + bx + c
x^2 -2x +
Comparing the two equations
a = 1 , b = -2, c = ?
c becomes the missing part
Divide b by 2
-2/2 = -1
square the result
-1^2
= 1 this is what to add to get a perfect square
x^2 -2x + 1
(x - 1)^2
A scale of 8cm:12cm would be a scale of 2/3. since this is the case, we can divide the scale drawing of the playground by the scale factor to get the length of the actual playground
12.4/0.6666 = 18.6
The answer is 18.6
