<span>Change 5'9" to 5.75 ft; let t = height of the tree
</span><span>You can use ratio here (corresponding sides of similar triangles):
5 x 75/ 5 = t/165
</span><span>cross multiply
5t = 5.75*165
5t = 948.75
t = 948.75/ 5
</span><span>t = 189.75 ft or 189 ft 9 inches</span>
Answer: the answer is 3.1 square meters.
Answer:
The answer is x=4
1.Move 7 to the other side (which makes it become a negative)
2.solve 19 -7=12
3.12 divided by 3=4
x=4
The temp. started at -20. If it rose +8 degrees, then it would be -20+8=-12, because since the -20 and +8 are opposites, you would subtract them and the answer would have the sign of the larger number which is -. so -12 is the answer.
