Answer:
5/12
Step-by-step explanation:
3/4 cover of the park and 1/3 of the trees are evergreen.
Therefore 3/4-1/3 = Fraction of the trees that is not evergreen.
3/4-1/3=5/12
Answer:
No
Step-by-step explanation:
Similar triangles must have the exact same angles
All angles must add to a total of 180° so to find x you can do 85°+64°=149° this means that 149°+x°=180° to find that you can do 180°-149° which equals 31°.
Then you do the same for the second triangle
1. 26°+85°=111°
2. 180°-111°=69°
because 69 and 31 aren't the same number these triangles aren't similar
similar triangles must have all the same angle amounts.
