Answer:
8x³y³
Step-by-step explanation:
When the number is in parentheses, it means the exponent goes to all of the variables and numbers inside. So 2 squared is 8 and x squared and y squared are just written like that. I hope this helps clear things up...
4inches = 1/3 of a foot (4inches x 3 = 12 inches) - so she can cut 3 out of each foot
1 yard = 3 feet - so she can cut 3 x 3 = 9 out of each yard
18 x 9 = 162 pieces
Given:
(a+10) and (a+20) are supplementary
To find:
Each angle
Steps:
if 2 angles are supplementary that means they add up to 180°
(a + 10) + (a + 20) = 180
a + 10 + a + 20 = 180
2a + 30 = 180
2a = 180 - 30
2a = 150
a = 150/2
a = 75°
Now let's find value of each angle,
a + 10 = 75 + 10
= 85°
a + 20 = 75 + 20
= 95°
Therefore, the value of each angle is 85° and 95° respectively
Happy to help :)
If you need any help feel free to ask
This is a 90-60-30 triangle so the angle is 30 degrees.
