Question

plz plz solve sums for me plz plz ​

Answer 1

Step-by-step explanation:

in triangle. angle ratio are 1:2:1

consider, angle A = 1x

angle B = 2x

angle C = 1x

A+B+C=180°

x+2x+x=180

4x =180

x = 180/4

x = 45°

A =45, B= 90 , C= 45

supplementory angles:

consider supplementory angles as A=3x and B=2x.

A+B=180 (sum of two supplementory angles equal to 180)

3x+2x= 180

5x=180

x= 180/5

x=36

A= 3(36)= 108

B= 2(36)= 72

Mean:

first ten natural number are

1,2,3,4,5,6,7,8,9,10

Mean = sum of all observations/number of observations

Mean =(1+2+3+4+5+6+7+8+9+10)/10

= 55/10

= 5.5
