Answer:
12x -3
Step-by-step explanation:
To find the perimeter, we add up all the sides
2x+ 3x-2 + 2x+1 +5x-2
Combine like terms
12x -3
If you would like to know what was the original price of the shirt, you can calculate this using the following steps:
30% + 100% = 130%
130% of $22.40 = 130% * 22.40 = 130/100 * 22.40 = $29.12
The original price of the shirt was $29.12.
Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
