Answer:
An experimental group is a group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing.
Explanation:
Control group, the standard to which comparisons are made in an experiment. ... A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
The control group would be the group you keep control as you would not change anything about it throughout the course of the experiment. The experimental group you would give the experimental drug to.
Answer:
46 and 88° or 67 and 67°
Explanation:
An isosceles triangle has two sides of equal length and one other of a different length;
A triangle with such features also has 2 equal angles and one other;
If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;
All angles in a triangle sum to 180, so:
180 - 46 = 134
The two remaining angles constitute 134° collectively;
If they are equal, each angle can be found like so:
¹³⁴/₂ = 67
Each of the two equal angles will be 67°;
Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92
Then, the remaining angle can be found like so:
180 - 92 = 88
So the angles within the triangle are either:
46, 46 and 88°
or
46, 67 and 67°
