T= 60°
It is an equilateral triangle which means all sides and angles are equal
u= 10m
It is an equilateral triangle which means all sides and angles are the same
Answer:
2x3 =6 than 5x3=15 than you gonna add
Step-by-step explanation:
Answer:
70 degrees = a
Step-by-step explanation:
Triangle= 180 degrees.
Therefore, since a and the unmarked angle are congruent since it is an isosceles triangle, we subtract 40 from 180, with a result of 140. With 140, we divide by 2 to find the degrees for both the unmarked angle and angle a, since they are congruent. 140/2 = 70, Angle A will equal to 70 degrees
Adds 4 each time and 5-4=1 so nth term is 4n + 1
Let the sum of the 10 numbers be x, then
x/ 10 = 1445
x = 1445 x 10 = 14450
New mean = (14450 + 1500)/11 = 15950/11 = 1450
