Let's write an inequality, such as follows: x < sqrt(50) < y. Square both sides of the equation. We get x^2 < 50 < y^2. Obviously, x is between 7 and 8. Also notice, that for integers a,b, (ab)^2/b^2, equals a^2. So let's try values, like 7.1. Using the previous fact, (7.1)^2, equals (71)^2/100. So, (7.1)^2, equals 50.41. Thus, our number is between 7 and 7.1. We find, with a bit of experimentation, that the square root of 50, is 7.07.
Angle sum property = Sum of the three angles of a triangle will be equal to 180° .
Using this let us find out the measure of x .
Measure of first angle = 101°
Measure of second angle = 38°
Measure of third angle = x
Answer:
5/12
Step-by-step explanation:
Assuming the each number is equally likely
1,2,3,4,5,6,7,8,9,10,11,12
There are 12 numbers on the spinner
Number less than or equal to 5: 1,2,3,4,5
There are 5 choices
P ( # < = 5) = Number less than or equal to 5/ total
=5/12
