Answer:

28 degrees

Step-by-step explanation:

step 1

Find the measure of angle 1

m\angle 1+65^o=180^o ----> by supplementary angles

m\angle 1=180^o-65^o=115^o

step 2

Find the value of x

(10x+5)^o=m\angle 1 ----> by corresponding angles

substitute

(10x+5)^o=115^o

10x=110\\x=11

step 3

Find the measure of angle 2

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

m\angle 1+m\angle 2+(4x-7)^o=180^o

substitute

115^o+m\angle 2+(4(11)-7)^o=180^o

m\angle 2=180^o-152^o=28^o

katovenus [111]
Hey there! :) The answer to your question is $12 per pound. To find a unit rate you divide $60/5= $12. To double-check, 1 pound is $12, 2 pounds is $24, 3 pounds is $36, 4 pounds is $48, and lastly 5 pounds is $60. I hope you have a great day, and keep smiling! :D Also hoped I helped! ;)
