Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
Since we can see that 41 degrees plus angle 2 equals 180, we can solve to find that angle 2 =139 degrees. angle 3 is equal to angle 2, so it is also 139 degrees (since they are across from each other and are made of the same two lines). For the same reason, Angle 4 is equal to 41 degrees.
Answer:
12.86
Step-by-step explanation:
this is rounded to the nearest hundredth
To right 1.6 as a percentage u would write 6
Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
