Answer:
x = 21º
Step-by-step explanation:
∆ ABC is isosceles therefor
Angles B and C are congruent
(180 - 18)/2 = 162/2 = 81º
------------------
∆ BCD is equilateral therefor all angles are 60º
---------------------------
x = = 81 - 60
x = 21º
Answer: 20
Step-by-step explanation:
Let the total number of pencils that Jackson has be represented by x.
Since 20% of his pencils are broken which equals 4. This can be written and represented in an equation as:
20% of x = 4
20/100 × x = 4
0.2x = 4
x = 4/0.2
x = 20
There are a total of 20 pencils
