Answer:
175 cm
Step-by-step explanation:
to the nearest ten means we look at the ones digit
since it has to round to less than 180, we know that the number cannot be greater than 180
the number cannot be less than 170 because if it were 169 it would no be able to get to 180 by rounding to the nearest 10 since it is more than 10 away
so we have the numbers 170 - 179 to work with
using rounding, 170 - 174 would all round to 170
175 - 179 would round to 180
the least number from 175 - 179 is 175, so that is our answer

Answer:
Angle 12 is 45 degrees
Angle 13 is 90 degrees
Angle 14 is 45 degrees

Obtuse= >90 degrees
Acute= <90 degrees
Right= 90 degrees
<em>GCF = 45</em>
- Step-by-step explanation:
<em>90 = 9×10 = 3²×2×5</em>
<em>135 = 45×3 = 9×5×3 = 3²×5×3 = 3³×5</em>
<em>GCF = 3²×5 = 9×5 = 45</em>
