Answer:

105 degrees

Step-by-step explanation:

well if we take a look at this

we know for sure that every triangle must have a total angle measurement of 180 degrees

so if we take the information we have and we add those together

55 + 20

that will give us

75

then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it

180-75

giving us 105 degrees as the third measurement of the angle in the triangle

Answer:

the third measure is 105°

Step-by-step explanation:

All <em>measures</em> of a triangle add up to 180°

A+ B + C = 180

20 + 55 + C = 180

75 + C = 180

C = 105°

A two-factor study with two levels of factor A and three levels of factor B uses a separate group of n = 5 participants in each
Mashcka [7]

Answer: There are 30 participants are needed for the entire study.

Step-by-step explanation:

Since we have given that

Number of levels of factor A = 2

Number of levels of factor B = 3

Number of participants in each treatment condition = 5

So, the number of participants are needed for the entire study is given by

2\times 3\times 5\\\\=6\times 5\\\\=30

Hence, there are 30 participants are needed for the entire study.
