3/5 is equivalent to 0.6
This is because if you times 2 to the numerator and denominator(top and bottom of the fraction) you will get 6/10 which is 0.6
Answer:
B
Step-by-step explanation:
ABD (half of the rectangle) is a right-angled triangle.
so, Pythagoras applies.
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle) and in our case the line BD.
a and b are the 2 sides enclosing the 90 degree angle. in our case here the lines AD and AB.
so,
BD² = AD² + AB² = (6-1)² + (5-2)² = 5² + 3² = 25 + 9 = 34
BD = sqrt(34)
Answer:
zx=115'
Step-by-step explanation:
supplementary angles add up to 180'
