Question

Tolong bantuin ka butuh bgt, sebisanya deh

Answer 1

Penjelasan dengan langkah-langkah:

1.

zA + zB = 90°

3x - 10 + x + 16 = 90°

4x = 90-6

x = 84/4 = 21°

..... zA = 3(21)-10 = 53°

2.

3x - 42 = 2x + 7

3x - 2x = 42 + 7

x = 49°

y + 42 = 3x - 42

y = 3(49) - 2(42)

y = 147 - 84

y = 63°

x + y = 49 + 63 = 112°

4.

sudut dalam berseberangan

= P2 dan Q4, P3 dan Q1

5. x = 38°

y = (180-38)/2

y = 142/2

y = 71°

z = x + y

z = 38 + 71

z = 109°

6.

3x - 10 + x + 8 = 180

4x = 182

x = 182/4

x = 91/2

x = 45,5°
