- Sum of Angles: 180(n - 2)°
Step-by-step explanation:
<u>Step 1: Identify</u>
We have a polygon, so n = 4.
- Substitute [SA]: 180(4 - 2)°
- (Parenthesis) Subtract: 180(2)°
- Multiply: 360°
This tells us the sum of all angles in the shape.
<u>Step 2: Solve for </u><em><u>x</u></em>
- Set up equation: 90° + 93° + 89° + x° = 360°
- Combine like terms: x° + 272° = 360°
- Isolate <em>x</em>: x = 88°
Answer:
$1251.59
Step-by-step explanation:
tax percent = 6.7%
cost price of watch = $113
tax amount = tax percent of total price
=6.7 % * 1173
=6.7/100 *1173
=78.591
Now find total cost of a watch with tax
total cost = tax amount + original cost price
=$78.591 + $1173
=$1251.59

Answer:
x = 9
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal if m is parallel to n
6x+5 = 7x-4
Subtract 6x from each side
6x -6x+5 = 7x-6x-4
5 = x -4
Add 4to each side
5+4 =x-4+4
9 =x
Answer:
-8/9
Step-by-step explanation:
-1 1/8
=> - 9/8
=> Multiplicative inverse of 9/8 is:
=> - 8/9 [Sign does not change only the numerator goes to the denominator and denominator to the numerator]
=> -8/9 is the multiplicative inverse of -1 1/8
