The one with the word bank is in this order, right angle, acute angle, straight angle and then obtuse then you try to guess an estimate a right angle is always a 90 degree angle and a straight angle is always 180 degrees the given part of the angle would be subtracted by 180 for example 180-130 which means X= 50 degrees
6x + ( 3x - 9) = 90°( being complementary angles )
6x+3x -9 = 90°
9x = 90° + 9
x = 99 / 9
x = 11
Answer:
The answer is E.
Step-by-step explanation:
If the game costs $10 originally then the following would be true:
B = $10
$10.00 x .18 = $1.80 so the discount is $1.80
10.00 - 1.80 = $8.20
To answer this, you will represent the new side length of the square as x + 6.
To find the area you will multiply (x + 6) by (x + 6).
To do this, you will multiply x and x, x by 6 twice and 6 by 6.
See the attached picture for the expression representing the area of the new square.
