Answer:
55°
Step-by-step explanation:
What we have are vertical angles. Vertical angles are angles directly opposite to one another.
Importantly, the measures of vertical angles are equivalent. Thus, set the expressions to each other and solve for x:
Subtract 3x from both sides:
Subtract 6 from both sides:
Divide everything by 4:
Flip:
Now, substitute this back into either of the equations since we know they are the same:
Multiply:
Add:
So, the angle is 55°
Answer: x < 360
Step-by-step explanation:
Let x be the total cost for the trip.
And, Here the total number of person = 4
Therefore, the cost for each person = x/4
And, According to the question, The cost must below $90 per person.
Therefore, x/4 < 90
⇒ x < 360
Which is the required inequality for the situation.
