Answer:
m∠HMO=102°
Step-by-step explanation:
we know that
In a Rhombus the diagonals bisect the angles and opposite angles are equal
In this problem
Angles HMO and HTO are opposite angles
m∠HMO=m∠HTO
m∠HTM=(1/2)m∠HMO ----> because the diagonals bisect the angles and opposite angles are congruent
substitute the values
[tex](5x+6)\°=(1/2)(12x-6)\°[/tex]
solve for x
[tex]10x+12=12x-6\\12x-10x=12+6\\2x=18\\x=9[/tex]
Find the measure of angle HMO
m∠HMO=(12x-6)°
substitute the value of x
m∠HMO=(12(9)-6)=102°
