∠1 and ∠2 are supplementary. ∠1=124°∠2=(2x+4)° Select from the drop down menu to correctly answer the question.
1 answer:
Remark Supplementary angles add up to 180o. Givens <1 = 124 <2 = 2x + 4 I imagine you are looking for either x or <2. Equation <1 + <2 = 180 Substitute the givens 124 + 2x + 4 = 180 Collect like terms on the left. 128 + 2x = 180 Subtract 128 from both sides 2x = 180 - 128 Collect like terms on the right 2x = 52 divide by 2 x = 52/2 x = 26 <<<<<<<<< answer <1 = 124 <2 = 2x + 4 = 2*26 + 4 <2 = 52 + 4 <2 = 56 <<<<<<<< answer We need choices if you want an exact answer.
