Answer:
the answer is the first one I think but I'm pretty sure
It could be either y = 12.75x or y = 13x. Check if you made a typing error because these rates are both better than B
Answer:
xº=71º
Step-by-step explanation:
Take the triangle BDH
Once the sum of interior angles of a triangle is 180º:
40º+31º+yº=180º
71º+yº=180º
yº=109º
Once yº and xº are supplementary angles (add up to 180º):
yº+xº=180º
109º+xº=180º
xº=71º
