Answer:
x = 100°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7, hence
sum = 180° × 5 = 900°
Sum the given interior angles and equate to 900
x + 155 + 116 + 135 + 135 + 116 + 143 = 900
x + 800 = 900 ( subtract 800 from both sides )
x = 100°
Answer:
2y-5
Step-by-step explanation:
friend: y
Brother: y-5
y+y-5
aka
2y-5
Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
Answer:
its C
Step-by-step explanation:
because 180⁰-40⁰=140⁰
Her weekly sales is X dollars
10% as a decimal is 0.10
Total commission is 0.10X ( 10% times weekly sales)
You then need to add that to her base pay of $140.
The equation is: w = 0.10x + 140
