Answer:
Angle D is 45 degrees. The side length is 9 in.
Step-by-step explanation:
In a rotation, side lengths and angles do not change.
The tree diagram is constructed and attached below in the image.
First we have to make a choice out of 3 subjects, so the probability of choosing art as the first subject is 1/3.
Once we have chosen art as the first subject, we have two choices. So the probability of choosing each option now is 1/2. Thus, the probability of choosing math, science is 1/2.
The probability of choosing the projects in order of art, math, science = 1/3 x 1/2 = 1/6
Therefore, the probability that the projects are in order of art, math, science is 1/6 (one over 6). So first option gives the correct answer.
Answer:
Step-by-step explanation:
B + 87 +78 +66 = 360
B = 129 °
the angle next to B then is
180 = 129 + b '
51 ° = b '
A + 61 + b ' = 180
A = 68 °
71 is the answer. If you round it, it would be 70.
A) high transparency of visible light
significance= allows photosynthesis to happen and speed up chemical reactions
b) high cohesion because of hydrogen bonding
significance= transport of water relies on water being pulled up around the plant.
