Urgent! triangle abc has angle measures as shown

(a) what is the value of x? show your work!
(b) what is the measure of angle c? show your work!

guys show your work ok you : *

all angles add up to 180, so add like terms and solve for x. plug x into C to find the angle C measure.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
