The measure of ∠bcd is 120°. the measure of ∠abc is 85°. what is measure of ∠bac?

35°

Step-by-step explanation:

<BCD + <C = 180° (angle on a straight line )

120° + <C = 180°

<C = 180° - 120° = 60°

<BAC + <ABC + <C = 180° (sum of interior angles of a triangle)

<BAC + 85° + 60° = 180°

<BAC + 145° = 180°

subtract 145° from bothsides

< BAC = 180° - 145° = 35°

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

the answer is c.
