Question

In the figure AB is parallel to CD. BC is parallel to AE. angle ABD measures (3x+4). angle BCD measures (6x-8). angle EDF measures (7x-20). what is the degree measure of angle BCD?
Guys I really need ur help. my test is tomorrow and I've been stuck on this question since yesterday. I literally am about to have a mental breakdown

Answer 1

Answer:

The measure of angle BCD is $68.5\°$

Step-by-step explanation:

step 1

Find the value of x

we know that

$m$ -----> form a straight line

substitute the values

$(3x+4)\°+(6x-8)\°+(7x-20)\°=180\°$

$(16x-24)\°=180\°$

$16x=180\°+24\°$

$16x=204\°$

$x=12.75\°$

step 2

Find the measure of angle BCD

$m$

substitute the value of x

$m$
