Answer:
Do the same thing for the other exercises and you should find the results. They are all complimentary angles, that means if you sum the two equations representing the angles of each exercise they will be equal to 180º always
Step-by-step explanation:
3. notice 2x is complimentary of 2x + 80 because 2x is opposed to that blank space that compliments it.... I'm bad at explaining, I'll just show.
2x + 2x + 80 = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 25º
so then:
2x = 2*25
2x = 50º
and:
2x + 80 = 50 + 80
2x + 80 = 130º
Answer:
train A is 403
and train B is 72
because if the total weight is 479 and train A is heavier than train B with a difference of 403 to get their weights each, you'll say 479( total amount of weight) - 403( the difference) which or = 72...
where you have A as 403 and B as 72
