So, we know that

4/5n = 2/3

n = 2/3 x 5/4 . . . . .. if fraction is moved to other side of the equation the numerator and denominator will be swithced

n = 10/12 ......................... divide numerator and denominator by 2

n = 5/6

The answer is Fraction 5 over 6

If the measure of DAC is x and the measure of CAB is (2x – 30), what is the value of x? (HINT** remember how we label angles, th

Scorpion4ik [409]

Answer:

Step-by-step explanation:

∠ BAD = 90° and

∠ DAC + ∠ CAB = ∠ BAD, that is

x + 2x - 30 = 90

3x - 30 = 90 ( add 30 to both sides )

3x = 120 ( divide both sides by 3 )

x = 40 → b

Answer:

48 degrees

Step-by-step explanation:

First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.

Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.
