Answer:

∠a=40°

Step-by-step explanation:

complement of angle a=90-a

supplement of angle a=180-a

90-a=1/2(180-a)-20

multiply by 2

180-2a=180-a-40

180-180+40=-a+2a

a=40

What is the LCD of 5/12 and -9/16 ?

Andreyy89

The least common denominator of 5/12 and -9/16

The answer is 48.

Now, we have to change the numerators also to make this a equal fraction to the first ones we had.

5*4 = 20
12*4 = 48

20/48

-9*3 = -27
16*3 = 48

-27/48
