The measure of the supplement of an angle exceeds three times the measure of the complement of the angle by 12. Find the measure

satela [25.4K]

Answer:

64.5°

Step-by-step explanation:

The supplement of angle x is 180-x. The complement of the same angle is 90-x, which is 90 less than the supplement.

We can let 'a' represent half the measure of the supplement. Then 2a is the measure of the supplement, and we are given the relation ...

2a -(3(2a-90)) = 12

2a -6a +270 = 12 . . . simplify

258 = 4a . . . . . . . . . . add 4a-12

a = 64.5

The measure of half the supplement is 64.5 degrees.

Additional comment

Then the supplement of the angle is 129°, and the angle is 51°. Its complement is 39°. 3 times the complement is 117°, which is 12° less than the supplement, as required.

There are many ways to assign the variable(s) in this problem. Here, we chose one that is pretty direct: the value of the variable answers the question. If you let the variable represent the angle, its complement, or its supplement, then additional work is required to answer the question after the value of the variable is found.

The length of a rectangular fenced enclosure is 12 feet more than the width. If Farmer Dan has 100 feet of fencing, write an ine

EastWind [94]

Let l length, w width, p perimeter:

l=12+w

2(l+w)=p

2((12+w)+w)= 100

2(12+2w)=100

12+2w=50

2w=38

w=19

l=12+w=12+9= 21

l=21

What is the difference? -6-(11)

lisabon 2012 [21]

Answer: $=-17$

Step-by-step explanation:

The first thing you must remember is the mulplication of signs. You know that:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:

$-6-(11)=-6-11$

Now, you need to add these numbers. And the result obtained is:

$=-17$

Which graph represents the function y= 2x-4?sty すす0-3xits : :os : ;-32pr ftーVetーTT it tie。pttーT-it-T +--+-

Sergio039 [100]

Solutions

You have been given the y-intercept of -4. The meaning of this is that the given line will go through the point (0, -4). Plug in 1 for x and find y.

$
y = 2x - 4

y = 2 * 1 - 4

y = 2 - 4

y = -2$


In graph C,= x = 1, y = -2

Graph C is the correct answer.
