Answer:
x = 17
Step-by-step explanation:
5x + 29 + 2x + 32 = 180 (linear pair means that these angles add up to 180 cos they are in a line)
7x = 119
x = 17
20,000,000+400,000+80,000+4,000+100+60+3
Answer:
B
Step-by-step explanation:
tan45° = 10/x
=> 1 = 10/x
=> x = 10
=> y^2 = 10^2 + 10^2 = 200
=> y = 100*sqrt(2)
=> b
