Mean is the average so add the numbers and divide by 9.
Mean = 25
Step-by-step explanation:
as the other triangle is Isosceles triangle which means it's two sides are equal and two angles are equal so
to find its 3rd angle apply angles sum property on it
according to which
2(68) + x = 180
136 + x = 180
x = 180 - 136
x = 44°
also we know, the other triangle is right angled triangle
so, it's one angle is 90° and 2nd angle is 44° (Vertically opposite angle)
therefore to know measure of angle 2 apply angle sum property of triangle in it too.
so,
90 + 44 + angle 2 = 180
134 + angle 2 = 180
angle 2 = 180 - 134
angle 2 = 46°
therefore, angle 2 is 46°
hope this answer helps you dear!
Answer:
The smallest possible value for x is 
Step-by-step explanation:
we know that
The <u>Triangle Inequality Theorem</u>. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
so
The value of x must be greater than 
so
If x must be a whole number
therefore
The smallest possible value for x is
