Find the area of QRS. Round the answer to the nearest tenth.

Tema [17]

Answer:

Option C

Step-by-step explanation:

Area of a triangle given with measures of 2 sides and angle between these sides will be,

Area of a triangle = $\frac{1}{2}\text{(a.b)sinC}$

Here, a and b are two sides of the triangle and C is the angle between these sides.

From the figure attached,

a = 6, b = 9 and m∠C = 110°

Substitute these values in the formula,

Area of ΔQRS = $\frac{1}{2}\text{(a.b)sinC}$

= $\frac{1}{2}{(9\times 6)\text{sin}(110^{\circ})}$

= 25.37

≈ 25.4 square units

Therefore, Option C will be the answer.

What is m in 4/5m=2/9 is it 5/18

Romashka [77]

$\frac{4}{5} m = \frac{2}{9} \\ \\ \frac{4m}{5} = \frac{2}{9} \\ \\ 4m = \frac{2}{9} \times 5 \\ \\ 4m = \frac{10}{9} \\ \\ m = \frac{10}{9 \times 4} \\ \\ m = \frac{10}{36} \\ \\ m = \frac{5}{18} \\ \\$

The final result is: m = 5/18 or 0.2778.
