Hello!
We know that the angles in a rectangle are 90°
Since they are 90° then the two separate angles add to 90
4x - 12 + x + 2 = 90
Combine like terms
5x - 10 = 90
Add 10 to both sides
5x = 100
Divide both sides by 5
x = 20
Now we put x into the two angles
x + 2 = ?
(20) + 2 = 22
4x - 12 = ?
4(20) - 12 = ?
80 - 12 = 68
The answers are
x = 20
4x - 12 = 68
x + 2 = 22
Hope this helps!
Answer:
300
Step-by-step explanation:
the nth term of a sequence is 3n^2 (where n only is squared), then the 10th term of the sequence is; 3 x (10)^2= 3 x 100 = 300.
