The value of .
We know that,
➪ 125° + + 30° = 180°
➪ + 155° = 180°
➪ = 180° - 155°
➪ = 25°
Therefore, the value of is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.
✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
The required inequality is
<em><u>Solution:</u></em>
Given that,
Cost of 1 cap = $ 5
Cost of 1 t-shirt = $ 10
Let "x" be the number of caps sold
Let "y" be the number of t-shirts sold
The drama club needs to raise at least $500.00 for the trip
Based on this information, we can frame a inequality as:
number of caps sold x cost of 1 cap + number of shirts sold x cost of 1 shirt 500
Which means,
Here we used "greater than or equal to" symbol , because club needs to raise at least $ 500
They can raise 500 or more than $ 500 also
Thus the required inequality is
