Answer:
m∠EAN =154°
Step-by-step explanation:
m∠EAN = m∠1 + m∠4 + m∠6
as given in figure we can see that m∠EAN constitute three angles angle 1, 4 and 6
hence m∠EAN will be sum of these three angles.
Given
m∠1=57°, m∠4=85°, m∠6=12°.
m∠EAN = 57° + 85° + 12° = 154° (answer)
Answer:
£5 : £25
Step-by-step explanation:
Sum the parts of the ratio, 1 + 5 = 6 parts
Divide the quantity by 6 to find the value of one part of the ratio
£30 ÷ 6 = £5 ← value of 1 part of the ratio, thus
5 parts = 5 × £5 = £25
Thus 1 : 5 = £5 : £25
Actually Welcome to the concept of areas,
we know that, area of rectangle = length * width,
here, length = x-2 and width = x-1
hence, area = (x-2) (x-1)
==> area = x^2 -x -2x +2
==> Area = x^2 - 3x + 2
hence the Option D.) is correct
