two angles are supplementary if their sum is180.the larger angle measure four degrees more then seven times the measure of a small angle.if x represents the measure of the smaller angle and these two angle are supplementary angle find the measure of each angle. the smaller measure the larger measure
help me please
We are given the smaller angle as x . Let the larger angle be y As x and y are supplementary so \[x+y=180.............................(1)\] the larger angle measure four degrees more then seven times the measure of a small angle.so \[y=7x+4....................(2)\]From first equation we get \[y=180-x\] Let's substitute this in second equation we get \[180-x=7x+4\] @ariana-help can you find x now?
i dont get it
@ariana-help tell me which part you don't get?
wat do i got to muli the numbers with
Did you understand how I got the last equation?
wat the answer
Let x be the smaller angle and 180 - x the larger of the two supplementary angles. 180 - x = 7x + 4 180 - 4 = 7x + x 176 = 8x 22 = x ------> smaller measure 180 - x = 158 ----> larger measure
it wrong
22degrees & 158 degrees are the right answer.
no it was not
130 and 50
Post your work and answers, please. I would like to compare it to mine to pinpoint my error. Thanks.
the larger angle measure four degrees more then seven times the measure of a small angle. --> from the problem as posted Your answers -->130 and 50 Checking your work: the larger angle measure four degrees more then seven times the measure of a small 130 = 4+ 7(50) 130 = 4 + 350 130 = 354 Your answer is NOT correct. Check to see if the problem is correctly posted.
