This is simple division to do this you must know you multiplication. However the answer is 28 ;)
Answer:
75°
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 = 6 , then
sum = 180° × 4 = 720°
let x be the sixth angle, then sum and equate to 720°
150 + 100 + 80 + 165 + 150 + x = 720
645 + x = 720 ( subtract 645 from both sides )
x = 75
The sixth interior angle is 75°
Answer:
78
Step-by-step explanation:
the product of 6 and 13 =78
Answer:
Step-by-step explanation:
y = x .....(1)
.... (2)
By solving equation (1) and equation (2)
or 
x = 0, x = 1
y = 0, y = 1

Hello,
Let y=sin^(-1)(12/13.
==>sin y=12/13
==>cos y=√(1-(12/13)²)=√(25/169)=5/13
Answer 5/13
