Answer:
(1) equilateral triangle
Step-by-step explanation:
Firstly, we will find all angles of triangle BCD
we are given
m<C=60
m<A=35
m<ABD=25
we know that sum of all angles in any triangle is 180
so, we get
m<A +m<ABD+m<DBC+m<C=180
we can plug values
35+25+m<DBC+60=180
m<DBC=180-120
m<DBC=60
now, we can find other angle
m<DBC+m<C+m<CDB=180
now, we can plug values
60+60+m<CDB=180
m<CDB=180-120
m<CDB=60
So, we can see that
m<C=m<DBC=m<CDB=60
so, all angles are equal
so, triangle BCD is an equilateral triangle
Answer: 1. 286 different combinations of players are possible.
2. The probability of selecting a team of 5 girls and 5 boys is and the decimal is 0.4405...
Step-by-step explanation:
1. Number of girls is 6 and number of boys is 7.
So, the total number of players = 6+7 = 13
A team of 10 players is to be selected from the class.
So, the total possible number of different combinations of players will be:
2. Number of girls is 6 and number of boys is 7.
The possible number of teams by selecting 5 girls and 5 boys will be:
and the number of total possible teams of 10 players
Thus, the probability of selecting a team of 5 girls and 5 boys or
