Answer:
28 degrees
Step-by-step explanation:
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.The corresponding angles are the ones at the same location at each intersection.
In the figure ABD and EDF are corresponding angles. So they are equal
So equation the angle ABD and EDF , we get
(3x+4) = (7x-20)
Group the like terms,
3x-7x = -20-4
-4x = -24
x = 6
Thus BCD will be,
(6x - 8)
=>(6(6)-8)
=>(36-8)
=> 28 degrees
Answer:
D. 26
Explanation:
10% = 6.5
6.5 x 4 = 26
I don’t know but I’ll try to figure it out
Answer:
(Given m∠DCB = 105, m∠DAB = 75) m∠ADC=75, m∠AXY=105, m∠DYX=105, m∠BXY=75, m∠CYX=75, m∠ABC=105
Step-by-step explanation:
Definition of consecutive interior angles
Simplify. Combine like terms
7y - 3y = 4y
-12 + 9 = -3
----------------------------------------------------------------------------------------------------------------
4y - 3 = 0
Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.
4y - 3 (+3) = 0 (+3)
4y = 3
4y/4 = 3/4
y = 3/4
-----------------------------------------------------------------------------------------------------------------
y = 3/4 is your answer
-----------------------------------------------------------------------------------------------------------------
hope this helps
