x = 109
this is pentagon
the sum of the interior angles of a polygon is
sum = 180°( n - 2) where n is the number of sides.
sum = 180° × 3 = 540° thus
x + 121+ 108 + 102 + 100 = 540
x + 431 = 540
subtract 431 from both sides
x = 540 - 431 = 109
Answer:
okay first one is ,3
Step-by-step explanation:
Answer:
2m - 9
Step-by-step explanation:
To simplify this, we need to combine like terms. m + m = 2m and -4 - 5 = -9 so the simplified version would be 2m - 9.
no because it is not a right angled triangle.
this means angle A is not 90° so AB cant be a tangent.
