Answer:
x=65, y=60
Step-by-step explanation:
x=65--->corrosponding angles with the triangle
x+y+55=180--->linear pair
(65)+y+55=180
y=60
3/8 because 2+3+3=8. One pair of pants, one pair of shirt and one pair of shoes =3
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

Answer:
24 in
Step-by-step explanation:
formula
square root (74)² - (70)² = b
square root (5476 - 4900) = b
square root 576 = 24
