Answer:

A = 58 degrees

b = 51.9

c = 48.5

Step-by-step explanation:

To find A we simply just need to remember that all triangles add up to 180 degrees and we are already given two angles of the triangle so....

57 + 65=122

122+58=180

A=58

To find sides b and c we use the law of sines since we now know the angle of each side.

a=48

b=48\times\frac{sin65}{sin57} =51.87

51.87

7>5

51.9

b=51.9

c=48\times\frac{sin58}{sin57} =48.54

48.54

4

c=48.5

Hope this helps.

PQR is a triangle. PR = 13 cm, PQ = 12 cm and angle QPR = 30°<br> Calculate the length of QR.
Deffense [45]

Answer:

6.55 cm

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.

Cosine rule is used to show the relationship between sides and angles of a triangle. If a, b, and c are sides of a triangle, while A, B, and C are angles opposite to the corresponding sides. Then:

c² = a² + b² - 2ab*cos(C)

Given that PR = 13 cm, PQ = 12 cm and angle QPR = 30°, hence:

QR² = PR² + PQ² - 2(PR)(PQ)cos(∠QPR)

QR² = 13² + 12² - 2(13)(12)cos(30) = 169 + 144 - 270

QR² = 43

QR = 6.55 cm
