-12 = 6 + 2/3y
Subtract 6 from both sides
-18 = 2/3y
Multiply both sides by 3
-54 = 2y
Divide both sides by 2
-27 = y
Answer:
y
Step-by-step explanation:
Associative Property a(bc)=(ab)c
1/4(4y)=(1/4(4))y
y

Why'd you put it as math dude
To solve this problem, you must know that an inscribed angle equals 1/2 of the arc that it intercepts.
Therefore, because <ABC intercepts arc ADC, we know that
the measure of angle ABC = 1/2 * (measure of Arc ADC)
OR, when the values are substituted into the equation
165 = (1/2) (5)(x-3)
When simplified, this equation equals
330 = 5x - 15
345 = 5x
x = 69
Therefore, your answer is the second option, that x = 69 degrees.
Answer:
90 degrees
Step-by-step explanation:
Sum of the angles in a triangle = 180°
Opposite angles are equal
For two parallel lines and a transversal,
corresponding angles are equal, and
alternate angles are equal.
45+45=90.
180-90=90
Plus, you can see that the angle forms a perfect 90 degree angle.
