Find Angle X On The Given Figure M class=

Sagot :

Answer:

x = 51°

Step-by-step explanation:

In a rhombus, the diagonals bisect the angles, thus

∠ BAE = ∠ DAE = 39° , then ∠ A = 78°

∠ ADE = ∠ CDE = x , then ∠ D = 2x

In a rhombus, consecutive angles are supplementary

∠ A and ∠ D are consecutive angles , thus

78 + 2x = 180 ( subtract 78 from both sides )

2x = 102 ( divide both sides by 2 )

x = 51°

Answer:

X=51
