2/3 of a box per 30 secs
2/3 times 2 = 4/3 = 1 1/3
The measure of ∠C using sine rule formula and as shown in the triangle is 39.8°.
<h3>SINE RULE FORMULA</h3>
The sine rule formula gives the ratio of the sides and angles of a triangle. The sine rule can be explained using the expression, a/sinA = b/sinB = c/sinC,
From the diagram, to calculate the measure of the ∠C, we use the sine rule formula.
- b/sinB = c/SinC............ Equation 1
From the diagram,
Given:
Substitute these values into equation 1 and solve for angle C
- 9/sin105° = 6/sinC
- sinC = (sin105°×6)/9
- sinC = 0.64
- C = sin⁻¹(0.64)
- C = 39.8°
Hence, ∠C is 39.8°.

Each square is 9 because you want to multiply 3x3 so you need to then take 9 and multiply it by the 6 squares so 9x6 is 54 therefore the correct answer is D
Answer: 4 / 5
Step-by-step explanation: 1) For a right triangle, the ratio sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) x is the angle. In this case: A
3) As per the figure, the opposite leg to tha angle A measures 28
4) As per the figure, the hypotenuse measures 35
5) Calculations:
sin(A) = 28 / 35
Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5
