Answer:
The shadow of the building = 192 ft.
Step-by-step explanation:
∵ There is a proportional relation between the heights of the tree and the building and their shadows

Answer:
£67.50

On each metre of material, the shop makes a profit of ...
£6.90 -4.65 = £2.25
So, for 30 metres, the profit will total ...
30 × £2.25 = £67.50
A profit of £67.50 would be made on a 30-metre roll of material.
Answer:
x = 17°
Step-by-step explanation:
<u>Angles And Parallel Lines
</u>
If two parallel lines are crossed by a third line, corresponding angles are congruent. Also, consecutive angles are supplementary
We can clearly see in the image provided, being w and b parallel, that the corresponding angles (4x-3) and 65° are congruent. We can express that relation as

Operating

So the value of the angle x is 17°
X^2-3x = x(x-3)
x^2-9 = x^2 - 3^2 = (x-3)(x+3)
HCF = x-3
