<span>There is not a property of "1" for addition, but the identity property in this case uses "0" instead. If a number is increased by 1, the value will necessary be increased or decreased by the amount added or subtracted. However, if the number either adds or subtracts zero, then value will be left unchanged. Examples: 3+1 = 4, but 3+0 = 3,</span>
40min*1.05=42min they spent 42 min together
ps: check the multiplication it's 01:30 and I did that in head
Answer:
h = 16.92 m
Step-by-step explanation:
If you mean to man horizontal line of sight then the height of the tree is:
h = 2m + x
x is one right side and second is distance from the base of a tree 32m.
Tangence in this right triangle is:
tan 25° = x / 32 => x = 32 · tan 25° = 32 · 0.4663 = 14.92m
h = 2 + 14.92 = 16.92m
God with you!!!
