Given that j || k, what is the measure of the missing angle?
2 answers:
60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.
Answer:
the measure of the missing angle is 60°
Step-by-step explanation:
GIVEN : j || k
solution :
We will use the property of linear pairs
120° + ∠1 = 180° (sum of linear pairs is 180°)
⇒ ∠1 = 180°- 120°
⇒∠1 = 60°
now since j || k
So, we can use corresponding angle properties
So, ∠? = ∠1 (corresponding angles are equal)
⇒∠? = ∠1 = 60°
Thus ? = 60°

Step-by-step explanation:
When x = 0,
3x + 7
= 3 ( 0 ) + 7
= 0 + 7
= 7
When x = 4,
3x + 7
= 3 ( 4 ) + 7
= 12 + 7
= 19
When x = 8,
3x + 7
= 3 ( 8 ) + 7
= 24 + 7
= 31
When x = 14,
3x + 14
= 3 ( 14 ) + 14
= 14 ( 3 + 1 )
= 14 ( 4 )
= 56
Answer:
The number is 45
Step-by-step explanation:
Let number = x
2/3 x = 30
x = 30/2/3
x = 30×3/2
x = 90/2 = 45
The number is 45
2/3 ×45= 90/3 = 30
