The power 0 only affects the x. x^0 = 1
-2 * 1 = -2
25
Here everything inside the brackets is affected by the 0.
(11abx)^0 = 1 There is nothing left over.
26
(xy)^0 = 1
(pq)^0 = 1
1 - 1 = 0
Answer:
y=30
x=60
Step-by-step explanation:
The triangle has all sides equal therefore all the angles are equal.
For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.
Therefore y=90-60
=30
x=180-(30+90)
=60
He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents
A
Step-by-step explanation:
here ,

now,
cosec(2-45°)=2
or,
1/sin(2-45°) =2
or,
1/sin2cos45°-cos2sin45=2
or,

or,
sorry I have that much qualifications to work on this question and hoping this much will make bit easy for you to solve it further
