Answer:
x = 81, y = 68 and z = 99
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle, thus
z = 63 + 36 = 99
x and z form a straight angle and are supplementary, so
x + z = 180, that is
x + 99 = 180 ( subtract 99 from both sides )
x = 81
The sum of the 3 angles in a triangle = 180°, thus
z + y + 13 = 180, that is
99 + y + 13 = 180
112 + y = 180 ( subtract 112 from both sides )
y = 68
Answer:
4989600
Step-by-step explanation:
First, find how many letters there are. There is 11 letters.
Next, find which letters are repeated and if so, how many times. The letters O, R, and H are each repeated twice.
Since there are 11 letters, you must do 11 ! (factorial). There are 3 letters that are repeated twice, so you must divide by 2 ! 3 times.
Your equation is:
11!/ 2! * 2! * 2!
It simplifies into 39,916,800/8 which is equal to 4989600
Your somewhat on the right track.
first is 3 choices each with 5 choices of veg. and each veg. can go with 4 choices of drinks.
so all you need to do is 3*5*4 =60 dinner combinations. i dont know how you got the 2
The number -1.28 is rational if it is an integer or decimal, so yes it is.
