Covert to a common denominator to help:
A LCD is 24.
12/24, 20/24, and 15/24
So 12/24, 15/24, 20/24
Convert back into their original denominators:
1/2, 5/8, 5/6.
F.
Answer:
Therefore 'x' is equal to 65.4°
Step-by-step explanation:
In Right Angle Triangle ABC
∠ B = 90°
AC = Hypotenuse = 12
CB = Adjacent Side = 5
To Find:
∠ C = x
Solution:
In Right Angle Triangle ABC Cosine Identity we have
Substituting the values we get
Therefore 'x' is equal to 65.4°
Answer:
x = 20°
Step-by-step explanation:
The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.
3x + 2x simplifies to 5x. 5x must equal 100.
100/5 = 20.
Therefore x = 20.
To get an equivalent fraction, multiply the fraction by a whole number. For example, you can do 2/3 times 2 to both sides which is 4/6.
