Step-by-step explanation:
6. 4. it's a 3,4,5 triangle
7 10x10 + 6x6 = 136
x = √136 = 11.7
To find the value of x, use the vertical angle theorem.
Vertical angles are congruent.
Thus we have:
6x - 10 = 5x + 1
Solve for x.
6x - 10 = 5x + 1
Add 10 to both sides:
6x - 10 + 10 = 5x + 1 + 10
6x = 5x + 11
Subtract 5x from both sides:
6x - 5x = 5x - 5x + 11
x = 11
To find the value of y, use corresponding angles thoerem.
When two parallel lines are crossed by a transversal, the angles in matching corners are correponding angles.
Corresponding angles are congruent.
Thus, we have:
y = 6x - 10
Substitiute x for 11:
y = 6(11) - 10
y = 66 - 10
y = 56°
ANSWER:
x = 11, y = 56°
9,500 is 15% less than the original price.
So it must be 85% of the original price.
£9,500 = 0.85 P
Divide each side by 0.85 :
P = £9,500 / 0.85 = £11,176.47
