The two triangles we can see in the diagram are similar, which means that their measurements are proportional. Line MN on the larger triangle MNP is 71.5ft long, and its corresponding line, MA, on the smaller triangle is 71.5-22= 49.5ft long. This means that the scale factor from the bigger to the smaller triangle is 71.5/49.5=13/9.
If line MP on the bigger rectangle is 97.5ft long, then its corresponding line, MB, must be 97.5÷13/9=67.5 ft long.
Therefore, x=67.5 ft
Answer:
2 degrees and 178 degrees.
Step-by-step explanation:
So, remember if 2 angles are supplementary, they equal 180 degrees. Let's call the smaller angle x, meaning the bigger angle, which is 89 times the size of the smaller angle, would be 89x. Now let's put that into an equation.
180 = x + 89x
We now have to group the x's together:
180 = 90x
Now in order to determine x, we have to divide by 90 on both sides.
X= 2
So we know that the smaller angle is 2, meaning that if the larger angle is 89 times the size, the larger angle would be 178.
X is your number
double it means 2 times x or 2x
add 4
2x+4
subtract my number
2x+4-x=x+4
subtract 3
x+4-3=x+1
the result is x+1 or your number plus 1
Answer:
Option D
Step-by-step explanation:
Option D is not proper scientific notation, as the exponent is not on the 10
