Answer:
3x-13+2x+4=116( the sum of two interior angle is epual to the sum of exterior angle )
5x =116-9
5x=107
x=21.4 degree
then
angle a= 3*21.4-13
a=51.2degree
angle b=2*21.4+2
b =44.8degree

Answer:
2.5cm
Step-by-step explanation:
area of a trapeziod = 1/2 (a+b)×h
a=1cm
b=5cm
h=?
area= 7.5cm^2
••••• 7.5cm^2=1/2 (6)h
7.5= 3h
then height = 7.5/3= 2.5cm
Answer:
c
Step-by-step explanation:
Pythagoras theroem
= 4√73
1. the mode is 100 because 100 is the most common number in that sequence
2. the mean is 193.8 because if you add up 108, 306, 252, 113, and 191 then divide that by 5 you get 193.8
