How do I find X and Y and what's the answer

siniylev [52]

Answer:

x = 77, y = 63

Step-by-step explanation:

x - 5 = 72 ( corresponding angles )

x = 77

The 3 angles on the straight line sum to 180°, that is

x - 5 + 51 + y - 6 = 180, that is

72 + 51 + y - 6 = 180

117 + y = 180 ( subtract 117 from both sides )

y = 63

PLEASEEEE HELP ME WITH THIS!!

Answer:

$x=\boxed {3.5}$

Step-by-step explanation:

Given:

AC = 5

BC = 6

DB = 4.2

∠ACD ≅ ∠BCD

AD = $x$

∵ ∠ACD ≅ ∠BCD

∴ CD is the angle Bisector of ∠ ACB

We know that, from angle bisector theorem that,

The angle bisector of an interior angle of a triangle divides the opposite side in two segments such that the two segments are proportional to the other two sides of the same triangle.

Therefore, the sides that are in proportion are given as:

$\dfrac{AC}{BC} =\dfrac{AD}{DB}$

Substituting the given values we get:

$\dfrac{5}{6} =\dfrac{x}{4.2}\\\\6x=5\times 4.2\\\\6x=21\\\\x=\dfrac{21}{6}=3.5\\\\\therefore x=3.5\ unit$

Therefore, the value of $x$ is 3.5.
