Answer:
y = 10
Step-by-step explanation:
<u>Since all sides are equal, that means all angles are 60 degrees. 60 + 60 + 60 = 180</u>
<u />
5y + 10 - 10 = 60 - 10
5y / 5 = 50 / 5
y = 10
Answer: y = 10
Answer:
50
Step-by-step explanation:
140- 40=100
100÷2=50
x=50

Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

Answer:
572000
Step-by-step explanation:
The population reduced by 12%, so (100-12)=88% is remaining.
So, 88% of 650000= 0.88 x 650000
= 572000
