Answer:12
Step-by-step explanation:
4 by 3
so 4x3=12
There chance for just getting across each row would be 50% but there chance of getting across completely is 1 in 18
Answer:
17 X 8 = 136^
area of a triangle
0.5 X b X h
0.5 X 8 X 17 = 68 cm^
136 - 68 = 68 cm^
total shaded area = 68 cm^
A and b are perpendicular meaning that they intersect forming 90
b and c are parallel meaning that the intersection of c and a is also perpendicular
11x - 9 = 90 degrees
solve
11x - 9 = 90
add 9 to both sides
11x = 99
divide both sides by 11
x = 9
Hope this helps
Answer:
Option C. x=7
Step-by-step explanation:
we know that
If PQ is parallel to BC
then
triangles APQ and ABC are similar
Remember that
If two figures are similar them the ratio of its corresponding sides is proportional
so
substitute the values
Solve for x
