The expression which gives the area of triangle QRS is \frac{1}{2} (9)(15)sin(20^{o} ).

We need to find the area of triangle QRS.

<h3>How do I find the area of a triangle using trigonometry?</h3>

The area of a triangle can be expressed using the lengths of two sides and the sine of the included angle. Area of Δ = ½ ab sin C.

Now, the area of the triangle QRS=\frac{1}{2} (9)(15)sin(20^{o} )

Therefore, the expression which gives the area of triangle QRS is \frac{1}{2} (9)(15)sin(20^{o} ).

Catherine wants to pass year for Ms. Ford's class and all she has left is to take the final Spring Final. If she earned a 60 on
Anvisha [2.4K]

Step-by-step explanation:

The final grade is the average of the two semesters.

70 = ½ (60 + x)

x = 80

So Catherine needs a Semester 2 grade of 80%.

The average of RC3 and RC4 is ½ (62 + 53) = 57.5.  This accounts for 90% of the Semester 2 grade.  The other 10% is the Spring final.

80 = 0.90 (57.5) + 0.10 (x)

x = 282.5

Catherine would have to score 282.5% on the Spring final in order to pass.
