Question

If one angle of a parallelogram is 105 find the another three angles and the ratio between the four angles.​

Answer 1

Answer:

Step-by-step explanation:

Opposite angles of a parallelogram are Equal.

Sum of angles of quadrilateral is 360.

If other two sides are x,

105 + 105 + x + x = 360

210 + 2x = 360

2x = 150

x =  75

Ratio = 105:75

         =6/5

Answer 2

second angle of parallelogram is 105° ______ opposite angle of parallelogram are congruent

third angle of parallelogram 180 - 105 = 75° _____ linear pair of angle forth angle of parallelogram is 75° _____ opposite angle of parallelogram are congruent

Ratio = 5 : 6
