I think that you should imagine what regular shape the figure would have been.
The fact that two sides are 9inches makes me think it would have been a square.
The area of a square is A= l² where l is the length of one side and A=area
A=9*9
A=81 in.²
Next, find the area of the part that is taken away,(it looks like a triangle). to find that, if the figure was a square, the length on top would be 9 not 5, so the length gone is 9-5=4, so the base of the triangle is 4,
If the figure was a square, the length on the other side would be 9 not 4 so the length gone is 9-4=5, so the height of the triangle is 5
the area of a triangle is A= 1/2bh, where A is area, b is base and h is height.
A=1/2*4*5 A=10 so the area of the part gone is 10 inches²
The area of the figure is the area of the square -the area of the triangle
A=81-10
A=71inches²

Answer: 684 divided by 57=12
Step-by-step explanation:(with reference to the figure)
To find 684 divided by 57 by partial quotients .
Here dividend= 684 and divisor =57
Step 1: Write easy factors of divisor that is nearest to the dividend as follows
57×2=114
57×3=171
57×5=285
57×10=570(nearest easy factor)
Step 2: Now subtract 570 from 684 ,we get 114 then subtract 114=57×2 from it we get 0.
Step 3: Adding the factors we have used in step 1 and 2 ,it will give required quotient=10+2=12
i.e. 684=57(10)+57(2)
Answer:
the answer is 2,500 cm^3
Step-by-step explanation:
Answer: A)Sin(33)= x/14
Step-by-step explanation:
Hi, to answer this question we have to apply the next trigonometric function:
sin α = opposite side / hypotenuse
Where α is the angle, the hypotenuse is the longest side of the triangle (in this case 14), and the opposite side to the angle is x.
Replacing with the values given:
Sin(33)= x/14
