Answer:
9 = x (assuming 15 is the hypotenuse)
Step-by-step explanation:
15^2 = 12^2 + x^2
225 = 144 + x^2
subtract 144 from both sides
81 = x^2
square root both sides
9 = x
3/4
Step-by-step explanation:
So if you simplify 1 1/2 you get 3/4. And if you multiply 3/4 by 2/2 you will get 6/4. Subtract 3/4 from 6/4 and you get 3/4.
has a reference angle of 30 degrees.
- Quadrant I: 30 degrees
- Quadrant II: 150 degrees
- Quadrant III: 210 degrees
- Quadrant IV: 330 degrees
Step 1) Find common denominator. In this case it was 28.
Step 2) Multiply 1/4 by seven to get 7/28 and then 2/7 by 4 to get 14/28.
Step 3) Add numerators: 7+14 to get 21
Step 4) Simpify your new added Fraction 21/28= 3/4
Your answer is 3/4
