<h3>Answer: x = 45</h3>

Work Shown:

x+x+90 = 180 .... all three angles of a triangle add to 180

2x+90 = 180

2x = 180-90

2x = 90

x = 90/2

x = 45

This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.

From a club 25 people in how many ways can a group of five members be selected to attend conference? A group of 5 members can be

IgorLugansk [536]

Answer:

²⁵C₅ = 53130

Step-by-step explanation:

number of people in the club = 25

number of people to be selected in the group to attend conference = 5

number of ways of selecting this group from 25 people is same as selecting 5 objects from 25 distinct objects = ²⁵C₅ (Selection)

= $\frac{25!}{5!(25-5)!}$

= $\frac{25!}{5!(20)!}$

= 21×22×23×5

= 53130

∴ <u>Number of ways of selecting this group from 25 people = 53130</u>
