1 answer:
raketka [301]3 years ago
3 0

Answer:

1. complementary

2. not complementary or supplementary

3. not complementary or supplementary

4. complementary

5. supplementary

Step-by-step explanation:

You can tell if two angles are complementary if their combined angle values add up to 90 degrees

A+B=90

You can tell if two angles are supplementary if their combined angle values add up to 180 degrees

A+B=180

If they don't add up to these values then they are neither complementary nor supplementary

A+B\neq 90        A+B\neq 180

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.
Rasek [7]

Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x - \frac{3}{4}) + \frac{5}{4} = -7

subtract \frac{5}{4} on each side of the equation


x - \frac{3}{4} = -8.25

add \frac{3}{4} on each side of the equation

x = -7.5


-7.5 - 3/4 = -8.25

-8.25 + 5/4 = <u>-7</u>


So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.


There you go! I really hope this helped, if there's anything just let me know! :)

Find the measure of CD⎯⎯⎯⎯⎯⎯⎯⎯.<br><br> A. 8<br> B. 6<br> C. 5<br> D. 7
oee [108]

Answer:

Using the property of intersecting secant:-

(DE)(CE)=(FE)(LE)

(4)(x-1+14)=(5)(x-4+5)

4(x+3)=(5x+1)

4x+12=5x+5

4x+-5x=5-12

-x=-7

x=7

So, CD=x-1=7-1=6

so,~your ~answer ~is ~B) ~6
