Find the value of A

Mathematics
1 answer:
Masteriza [31]3 years ago
5 0

Answer:

a = 5

Step-by-step explanation:

Angles A and B are the same at 45, a and b are also the same

The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.

sin(A)/a = sin(B)/b = sin(C)/c

Substitute the known values into the law of sines to find a.

SinA / a = sin(90) / 5√2

a = 5

Find the distance that the points is given on the graph ?
EleoNora [17]

From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:

\large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} +  {(y_2 - y_1)}^{2} } }

Substitute these points in the formula.

\large{ \sqrt{ {(2 - 4)}^{2}  +  {( - 1 - 0)}^{2} } } \\  \large{ \sqrt{ {( - 2)}^{2} +  {( - 1)}^{2}  } }  \\  \large{ \sqrt{4 + 1} \longrightarrow  \sqrt{5}  }

Hence, the distance is √5

Answer

  • √5
