Answer:
x = 117°
Step-by-step explanation:
The angle inside the triangle and 101° are adjacent and supplementary, thus
angle inside triangle = 180° - 101° = 79°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle , thus
x = 38° + 79° = 117°
To get the amount that remains by lunch time we proceed as follows:
Total amount of water Halle drinks is:
(1/4+2/3)
to add we put the fraction under the same denominator by multiplying the denominators
=4*3=12
thus
1/4+2/3
=(3+2*4)/12
=(3+8)/12
=11/12
The fraction water in the bottle when full is 1/1
thus the remaining amount will be:
1/1-11/12
=1/12
Answer is 1/12
given that 1 liter= 1000ml, the remaining amount will be
1/12*1000
=83 1/3 milliters
