Answer:
1.9
Step-by-step explanation:
pi = 180 degrees
pi/3 = 180/3
degree = 60
60/360 = 6
circumference: 2*6 = 12
12/pi = 3.81971863421
ans/2 = 1.90985931711
round: 1.9
Answer:
6 • (2x + y) Step-by-step explanation:
× = -t/p
Step-by-step explanation:
By collecting like terms you will have a new equation
h - t - h = px
Then both h will cut out leaving
-t = px
dividing both side by p will give you
x = -t/p
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = = 5
