Answer:
4.3
Step-by-step explanation:
first round
3.296 is 3.3
0.9785 is 1
3.3 + 1 = 4.3
Answer:
23°
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)
I can't help you if the table is not provided
First, break up the shapes into parts. The first one you see is 7 by 4 rectangle on the top.
A=l*w
A=7*4
A=28 for the rectangle, your not done
Now the triangle to the left
A=l*w/2
A=19*10/2
A=95
Now all you got left is the trapezoid, which area's formula is:
A=(b∧1+b∧2*h)/2
A=9+19*8/2
A=112.
Now you have the area for three of the figures, add them up:
112+95+28=235
So in total, the area of this figure is 235 cm^2
Answer:
Step-by-step explanation:
I will ASSUME that the units on 53 is angular degrees (53°) and that the internal angle below x is 90°
The drawing is certainly not to scale
sin53 = x / 49
x = 49sin53
x = 39.1331399...
x = 39 units (same units as 49)
