Graphing
Step-by-step explanation:
Refer to the image below!
Pemdas 1. parentheses: everything is already in parentheses. so next is exponents. 10×-2 is -20. and 10×6 is 60. so 4×-20 is the next step. it equals -80. and then 3×60 is 180. lastly,add -80 and 180 together. the answer should be 100 if i did that correctly.
1 - yes 100 and 75 are both collinear both are the same line.
2 - She can conclude that there both similar because the both go the same direction and both same shape.
3 - AB would equal 150 because the other one was 100 and the other angle was 25 down. So AB would equal 150.
Hope I helped
