Ok let us see it this way:
If x is the measure of the angle we require 
<span>The complement is 90 - x </span>
<span>one half of the complement is therefore 0.5(90 - x) 
</span><span>18 degrees less than one half of the measure of the complement is
0.5(90 - x) -18
</span>I hope this can be of good use

The measure of an angle is 44.6°. What is the measure of its complementary angle?
Leni [432]

The measure of the complementary angle to the angle 44.6° as given in the task content is; 45.4°.

<h3>What is the measure of the complementary angle as given in the task content?</h3>

It follows from the task content that the complementary angle to angle measure 44.6° be determined.

Unlike supplementary angles which add up to 180, complementary angles add up to 90°.

Hence, the required complementary angle is; 90°-44.6° = 45.4°.

Which is greater?<br> 1.4 or 1.41421356237
Westkost [7]

Answer:

1.41421356237

Step-by-step explanation:

After every decimal place value, or decimal point, there are infinite rows of invisible 0's

In 1.4, there are countless invisible 0's, which would look like this

1.40000000000000000...

Same for 1.41421356237

1.4142135623700000000...

So now, you can compare and see that 1.41421356237 has a 1 in the hundredths place, while 1.4 has a 0 in the hundredths place

Thus, 1.41421356237 is greater than 1.4

Can I please have help, I don't know how to solve this.<br><br> 3741 = P(P-1) over 2
STatiana [176]

Answer:

The values of P are -87 or 86.

Step-by-step explanation:

Given:

3741=\frac{P(P-1)}{2}

Multiply by 2 on both the sides. This gives,

3741\times 2=\frac{P(P-1)}{2}\times 2\\7482=P(P-1)

Now, use distribution property.

7482=P\times P - P\times 1\7482=P^2-P

Now, add -7482 on both sides,

P^2-P-7482=0

This is a quadratic equation of the form ax^2+bx+c=0 which can be solved using quadratic formula with a=1,b=-1,c=-7482

P=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\P=\frac{-1\pm\sqrt{(-1)^2-4(1)(-7482)}}{2(1)}\\P=\frac{-1\pm\sqrt{1+29928}}{2}\\P=\frac{-1\pm\sqrt{29929}}{2}\\P=\frac{-1-173}{2}\textrm{ or }P=\frac{-1+173}{2}\\P=\frac{-174}{2}\textrm{ or }P=\frac{172}{2}\\P=-87\textrm{ or }P=86

Therefore, the values of P are -87 or 86
