The average yearly growth rate of the height of the tree was 2.2 feet per year during the 7 1/2 years.
40 x 5280 = 211200 feet per hour
211200 / 3600 = 58.666 = 59 feet per second
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.
We get 20 and 45
