124+(2x+4) = 180
2x = 52
x = 26
Note: supplementary angles means that sum of the two angles is 180 degrees
These are both rational numbers, because they are (our could be written as) a fraction. 1.45 = 145/100
There is no smaller subset of real numbers that works, because the next smaller subset is integers, but these aren’t integers.
Hey there,
When finding the largest prime factor of a number, basically all you doing is find the divisible of the number. For example:
What are the prime factors of 8?
8
/ \
4 2
/ \ \
2 2 2
Hope that helps.

The computation of the equations is illustrated below.
<h3>How to illustrate the equation?</h3>
a. x - y = 1 .... i
x + y = -9 ..... ii
Subtract the equations
-2y = 10
y = 10/-2 = -5
Since x - y = 1
x - (-5) = 1
x + 5 = 1
x = 1 - 5 = -4
b. 3x + 2y = -9
x - y = -13
Multiply equation i by 1
Multiply equation ii by 3
3x + 2y = -9
- 3x - 3y = -39
5y = 30
y = 6
Since x - y = 13
x - 6 = 13
x = 13 + 6 = 19

Answer: Rate of change of Area of the triangle = 2.75cm~/min
Step-by-step explanation:
If the present height of the triangle is 22cm and the height increases by 5cm/min. It means the height was 2cm four minutes earlier: 5cm for 1st min + 5cm for 2nd min + 5cm for 3rd min + 5cm for 4th min = 20cm after 4min.
Therefore height equals 22 - 20 = 2cm four minutes earlier.
Using the same four minutes for the base. Since the base shrinks at 1cm/min, for the base to shrink to 10cm it means it was 14cm four minutes earlier.
The Area of a triangle is given by
A = 1/2 × base × height
Therefore Area= 1/2× 10×22 = 110cm~
Since it took four minutes to get to this area, the rate of change of the area will be 110÷4 = 2.75cm~/min
