Answer:
-4 8/9
Step-by-step explanation:
-4 8/9 is your answer. I hope this helps :) If so, I'd apprciate brainliest, but no pressure.
Given that the ladder is 10 ft long and the height of the wall is 8.5 ft, to find whether the ladder is safe resting on the window sill we use the formula:
sin x=opposite/hypotenuse
opposite=8.5 ft
hypotenuse=10 ft
thus
sin x=8.5/10
sin x=0.85
x=arcsin 0.85
x=58.21°
Since 58.21°<65° the we conclude that the ladder is very safe.
Answer:

14 4/9 x 4 = 57 7/9
Answer:
63/90 = 7/10
Step-by-step explanation:
63 = 3²×7
90 = 2×3²×5
The factor of 3² is common to both numbers, so the fraction reduces to ...
... 63/90 = (3²×7)/(3²×10) = 7/10
Answer:
Step-by-step explanation:
A=bh/2, b=y, h=8, A=40
