Here is the solution for the eqns.
Answer:
x=18
Step-by-step explanation:
Triangles add up to 180°, so 140+22+x=180 and then you simplify which is 162+x=180, then you subtract 162 on both side, getting x=18

Answer:
60
Step-by-step explanation:
Find the least common multiple between 12 and 15. In more layman terms, what whole number multiple do 12 and 15 share? The first one they share is 60.
Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
=
Note that AD = 33 - 22 = 11
Substitute values into the ratio
= = ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
= , substitute values
= = ( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A
