5.The measure of smaller angle is 87 degrees.
Step-by-step explanation:
Consider the provided information.
The provided angles are 3x degree and 2x + 25 degree.
Two angles are said to be Supplementary angles if their sum is 180 degree.
It is given that the provided angle are supplementary angles, thus
3x + 2x + 25 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 31
Now, substitute the value of x in first angle i.e 3x.
3(31) = 93
Substitute the value of x in the second angle i.e 2x + 25
2(31) + 25 = 62 + 25 = 87
Hence, the measure of smaller angle is 87 degrees.
Answer:
= 72a + 20s
Step-by-step explanation:
Given that;
a = number of adult tickets sold
s = number of student tickets sold.
According to given condition:
For first night;
=2(9a) + 5s
=18a + 5s
For second night:
= 3*18a + 3*5s
= 54a + 15s
Expression for total money of both nights:
= (18a + 5s ) + (54a + 15s )
Adding same terms:
= 72a + 20s
