As the sum of two complementary angles = a + b = 90
degree -------(1)
Difference of two complementary angles = a – b
According to question;
The difference of two complementary angles exceed the
sume (90) by 86.
So
a – b = 90 – 86 = 4 -------(2)
adding equation (1) and (2);
2a = 90 + 4 = 94
a = 94 / 2 = 47
putting a = 47 in equation (1);
47 + b = 90
b = 90 – 47 = 43
<span>
So angle a = 47 and
angle b = 43</span>

Given:
Faiz's total online shipping bill comes to £45.71.
He then receives discount of £15.90.
To find:
How much does he have to finally pay after the discount?
Solution:
We have,
Amount of bill = £45.71
Discount amount = £15.90
Now,
Final payment = Amount of bill - Discount amount
= £45.71 - £15.90
= £29.81
Therefore, Faiz's have tp pay £29.81 after discount.

Answer:
-4, 0
Step-by-step explanation:
The denominator is x^2+4x. This is zero when ...
x^2 +4x = 0
x(x +4) = 0
The zero product rule tells you the product is zero when the factors are zero.
x = 0
x +4 = 0 ⇒ x = -4
The denominator is zero for x=0 and x=-4.
