Answer 1

The values of the angles are as follows:

• x = 8.62
• x = 8.53
• m∠EDC =  70

How to find unknown angles?

1.

∠ABC = 108 degrees

Therefore,

3x + 2 + 10x - 6 = 108

13x - 4 = 108

13x  = 108 + 4

13x = 112

x = 112 / 13

x = 8.61538461538

x = 8.62

2.

∠ABC = 108 degrees

∠DBC = 10x - 20

Hence,

5x + 10x - 20 = 108

15x - 20 = 108

15x  = 108 + 20

15x = 128

x = 128 / 15

x = 8.53

Hence,

∠DBC = 10(8.53) - 20 = 65.33

3.

m∠EDC = m∠EDU + m∠UDC

m∠EDC = 32 + 38

m∠EDC =  70
