Answer 1

Jawaban:

3. a. 60°

b. 25°

c. 20°

d. 62,5°

4. a. 20°

b. 120°

c. 60°

5. a. 20°

b. 80°

c. 100°

d. 80°

e. 100°

Penjelasan dan langkah-langkah:

3. a. x = 30°

y = 90° - 30° = 60°

b. y = 65°

x = 90° - 65° = 25°

c. x = 70°

y = 90° - 70° = 20°

d. y = 27,5°

x = 90° - 27,5° = 62,5°

e. CBD = 18°

DBE = 90° - 18° = 72°

f. DBE = 48,5°

CBD = 90° - 48,5° = 41,5°

_______________________________

4. a. 6a + 3a = 180°

9a = 180°

a = 180° : 9

a = 20°

b. PQS = 6a

= 6 × 20°

= 120°

c. RQS = 3a

= 3 × 20°

= 60°

_______________________________

5. a. 5a + 4a = 180°

9a = 180°

a = 180° : 9

a = 20°

b. QTR = 4a°

= 4 × 20°

= 80°

c. RTS = 5a°

= 5 × 20°

= 100°

d. PTS = 4a°

= 4 × 20°

= 80°

e. PTQ = 5a°

= 5 × 20°

= 100°
