Which statement about the angle measures is true?
sures is true?
mzbac + m zacb= 85°
m_bac + mlabc = 850
m_bac + m_acb=950
m_bac + m abc = 950

for b its (t) and c its (d)

step-by-step explanation:

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

doubled

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
