A straight line equals 180 degrees, so the 3 angles in the picture need to equal 180.
X + 90 + 25 = 180
x +115 = 180
Subtract 115 from both sides:
x = 65
Answer:
x = 25
Step-by-step explanation:
14+10+17+9=50
+25=75
/5=15
or
5*15
5*5=25, leave the 5 carry the 2
5*1=5+2=7
75
Answer:
416
Step-by-step explanation:
6.5 x 4 x 8 = 208
208(2)=416
Answer:
512 is a perfect cube because 512 = 8 times 8 times 8
Step-by-step explanation:
A perfect cube is a number that can be rewritten as a product of three identical numbers.
For example: 8 is perfect cube as 8 can be rewritten as:
8 = 2 × 2 × 2
So, from the definition of the perfect cubes, the option that matches it is third option.
512 is a perfect cube as it can be expressed as the product of 8 three times.
512 = 8 × 8 × 8
Therefore, third option is correct.
All the remaining options doesn't fulfill the definition of perfect cubes.
