Answer:
area=22 peremeter=19 14/15
Step-by-step explanation:
The figure is a scalene triangle, and the exact length of side a is √13
<h3>How to determine the exact length of side a?</h3>
To calculate the length of a, we make use of the following law of cosine
a² = b² + c² - 2bc * cos(A)
Using the values in the figure, we have:
a² = 3√2² + 5² - 2 * 3√2 * 5 * cos(45)
Evaluate the expression
a² = 18 + 25 - 30
Evaluate the sum and the difference
a² = 13
Take the square root of both sides
a = √13
Hence, the exact length of side a is √13

Answer:
93. Divide 248 by 8. One eighth of 248 = 31.
June sold 3/8 of the 248 oranges.
If 1/8 = 31 and June sold 3/8 of the oranges.
Multiply 3 × 31. Therefore June sold 93 oranges.
