No nothing can go into 7 evenly except 7 but that doesn’t go into 20 evenly so your answer is no
Answer:
13
Step-by-step explanation:
A triangle is 180º. We have two angles; 60º and 60º
60+60 = 120
180-120 = 60º
This means that this is an equilateral triangle and all the sides are the same length.
13
Answer: Alternate exterior angles
Step-by-step explanation:
Let the length of segment AB be x.
BC then is AB + 6 or x + 6.
AC is AB + BC - 13 or x + x + 6 - 13 = 2x - 7
The sum of the three lengths is 78.
x + x + 6 + 2x - 7 = 78
4x - 1 = 78
4x = 79
x = 19.75
BC = x + 6 = 19.75 + 6 = 25.75
Answer: B. 25.75 mm
