Answer:
The value of x = 30°
Step-by-step explanation:
The value of first angle = ( 2 x)
The value of the second angle = ( x + 30)
Now, the given angles are VERTICAL ANGLES.
Also, by the definition, the VERTICAL ANGLES ARE CONGRUENT.
So, First Angle = Second Angle
⇒ (2 x ) = ( x + 30 )
or, 2 x - x = 30
⇒ x = 30
Hence, the value of x = 30°.
Equivalent
4:5 multiply both sides by 4 to get 16:20
it's D
You use distribute property, then add all like terms
31
1/4 of 124, ¨of¨¨ represents multiplication
so 1/4*124=124/4
which 124 divided by 4 equals 31
