Answer 1

Penjelasan dengan langkah-langkah:

3.

a. AOB = 2 × BCA = 2 × 25 = 50°

b. OAB = (180 - AOB)/2 = (180 - 50)/2 = 130/2 = 65°

c. ABC = (180 - BCA)/2 = (180 - 25)/2 = 155/2 = 77,5°

d. BAC = ABC = 77,5 °

..

4.

a. 2x + x + 90 = 180

3x + 90 = 180

3x = 90

x = 30°

..

b. PRQ = 2x

PRQ = 2(30)

PRQ = 60°

..

1.

(a) x = 1/2 × AOB

x = 1/2 × 80

x = 40°

..

(b) y = 25°

x = 2 × y

x = 2 × 25

x = 50°

..

(c) x = y = 35°
