40o

80o

100o

140o

Based on the given information that the ratio of x to y is 2:7, we can conclude that the angle x is smaller than the angle y. Since the options provided are all greater than 40o, we can eliminate them. Therefore, the correct answer is 40o.

Explanation

2. Besar sudut terkecil yang dibentuk jarum jam pada pukul 04.00 sama dengan…

1/8 sudut satu putaran penuh

1/4 sudut satu putaran penuh

1/3 sudut satu putaran penuh

1/2 sudut satu putaran penuh

The correct answer is 1/3 sudut satu putaran penuh. At 04.00, the minute hand is pointing directly at the 12 on the clock, while the hour hand is pointing at the 4. The angle between the hour hand and the minute hand is 1/3 of a full rotation because there are 12 hours on a clock and the hour hand moves 1/12 of a full rotation per hour. Therefore, the smallest angle formed by the minute hand is 1/3 of a full rotation.

4. Sebuah sudut sama dengan 2/ 7 sudut pelurusnya. Besar sudut itu adalah.....

72o

40o

45o

14o

The given statement states that an angle is equal to 2/7 of its complement. The complement of an angle is the angle that, when added to the given angle, forms a right angle (90 degrees). Therefore, if we let x be the given angle, the complement would be 90 - x. According to the statement, x = (2/7)(90 - x). Solving this equation, we find that x = 40 degrees. Therefore, the correct answer is 40o.

5. Perhatikan gambar di samping Pasangan sudut yang jumlahnya 180^o adalah ….

sudut P2 dan sudut Q1

sudut P1 dan sudut Q3

sudut P3 dan sudut Q2

sudut P4 dan sudut Q2

The correct answer is "sudut P3 dan sudut Q2". In the given image, it can be observed that sudut P3 and sudut Q2 are adjacent angles that form a straight line, which means they are supplementary angles. The sum of supplementary angles is always 180 degrees. Therefore, sudut P3 and sudut Q2 have a total measure of 180 degrees.

Based on the given information, we can see that AB is parallel to DC. Therefore, the alternate interior angles theorem states that angle CDB is congruent to angle ABD. Since angle ABD is not given, we can conclude that angle CDB is also not given. Therefore, it is not possible to determine the exact measure of angle CDB.
