Find the measure of angle a

quester [9]

Answer is 49.2

Total of all angles = 360

(x+16) + (x) + ( 6x-4) + (2x+16) = 360

10x + 28 = 360

X= 33.2

Angle A = x+16= 33.2+16= 49.2

Rhombus ABCD has a diagonal BD¯¯¯¯¯.

ELEN [110]

Answer:

Solution given:

m∠ADB=(4x−12)°

m∠CDB=(3x+6)°

m∠ADC =?

Since diagonal BD bisect the angle <ADC

m∠ADB= m∠ADC

(4x-12)°=(3x+6)°

4x-3x=6-12

x=12+6

x=18°

again.

<ADB=m∠ADB+ m∠ADC=4×18-12+3×18+6=120°

the m∠ADC =120°
