Answer:
x = 59, y = 59, z = 62
Step-by-step explanation:
This is an isosceles triangle, therefore, the angles that are across from the congruent sides are also congruent: x = y
We also know that by the Triangle Angle Sum Theorem, that all the angles of the triangle add up to equal 180 degrees.
Therefore, x + y + z = 180 and, subbing in our expressions gives us
2x + 31 + 2x + 31 + 5x - 8 = 180 and
9x + 54 = 180 so
9x = 126 and
x = 14
That means that x and y have measures of
2(14) + 31 = 59
If those are 59 each, then
z = 180 - 59 - 59 so
z = 62
Let's check and make sure that sum is in fact 180:
59 + 59 + 62 = 180
Complete the square
first isolate x terms
y=(x^2-4x)-9
complete square inside (take 1/2 of square of b )
-4/2=-2, (-2)^2=4
add 4-4 inside
y=(x^2-4x+4-4)-9
complete the square
y=((x-2)^2-4)-9
y=(x-2)^2-4-9
y=(x-2)^2-13
Answer:
4665 approx
Step-by-step explanation:
Given data
Total number of crashes= 16,370 automobile crashes
Percentage caused by distraction =28.5%
Let us find the number of crashes caused by distraction
=28.5/100* 16,370
=0.285* 16,370
=4665.45
Hence the number of crashes caused by distraction is 4665 approx
