There were two trees growing from seeds in a backyard. One tree grew at a rate of 1//2 of a foot every 2 years. The other grew 4
Ann [662]

Answer:

The height between the two trees will be 1.67 feet.

Step-by-step explanation:

What you do is you take the 1/2 have and times it by 6 because it is every two years that the tree grows 1/2 of a foot. So it will be 3 feet. The other tree grew 4 inches in 3 years so it will be 16 inches you will then have to make the 16 inches into feet to get 1 1/3. You will then minus the 3 feet and the 1 1/3 to get 5/3 or 1.67 feet.

What is the measure of the missing angle? <br><br> 115°<br><br> 35°<br><br> 75°<br><br> 40°
lions [1.4K]
Answer:
115

Explanation:
Angles in a triangle sum to 180
Add the two angles given and subtract it from the total sum of angles to find the missing interior angle -
75 + 40 = 115
180 - 115 = 65
Now that we have the interior angle, we can work out the exterior angle by subtracting it from 180
180 - 65 = 115
