Answer:
b = 74
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles in a triangle
b-44 + b+18 = b+48
2b-26 = b+48
Subtract b from each side
2b-b-26 =b+48-b
b-26 = 48
Add 26 to each side
b-26+26 = 48+26
b =74
2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.
G = (7h + 2f + 3c - 17.15)/2
