Answer:
vertical angles
Step-by-step explanation:
vertical angles is the angles opposite each other when two lines across
Answer:
10 quarters and 12 dimes :)
Step-by-step explanation:
First, the biologist must define the variables:
Dependent- this is what will be measured. So the biologist may want to measure the weight and height of the tomatoes, or the leaf area or the time it will produce the fruit.
Independent- this is what will differ in the experiment and what the biologist thinks will affect the dependent variable. In this case, the biologist will use new fertilizer on plant A, old fertilizer on plant B, and no fertilizer on plant C.
Controlled- these variables must be held constant because the biologist doesn’t want other factors to affect the growth of the tomato plant, thus, destroying the purpose of the experiment, tomato plant A, B, and C will have equal amounts of soil, water, and carbon dioxide, and exposure to sunlight.
After his experimentation, he will conclude which of the plant has better weight, growth, leaf, and fruit. If Plant A is the best tomato plant of them all, then he can say that the new fertilizer is more effective.
Answer:
a = 14, x = 55, y = 60
Step-by-step explanation:
a: Find the number that is between 10 and 18, 10 + 18 = 28 divide by 2 = 14, so a = 14
x: Due to corresponding angles theorem, so x = 55 degrees
y: Straight line is 180 degrees, and as we can see at the left side of the image there's a straight line where only 55 degrees was identified so 180 - 55 = 125 and since x = 55 degrees due to corresponding angles, the angle above y is 120 also due to corresponding angles. A quadrilateral is 360 degrees, so:
125 + 55 + 120 + y = 360
180 + 120 + y = 360
300 + y = 360
y = 60
