Answer:B
Step-by-step explanation:
Answer:
Step-by-step explanation:
12x - 3 = 180 - (7x - 26) supplementary angles
19x = 209
x = 11
m∠DEC = 12(11) - 3 = 129°
m∠BCE = 7(11) - 26 = 51°
M∠ADE = 129 - 72 = 57° exterior angle rule
m∠EDB = 180 - 57 = 123° supplementary angles
m∠DBC = 57° corresponding angle to ADE
Step by step:
6 - 2(x + 6) = 3x + 4
6 - 2x -12 = 3x + 4
6 - 12 = 5x + 4
-6 = 5x + 4
-10 = 5x
-2 = x
So, x = -2
Answer:
y-4=0.4(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
Small circle 2/4 = 1/2 and the big circle is 3/5 i hope this is correct. im truly sorry if this was wrong
