90o
63o
60o
26o
0o
Correct answer is B
tan θ - 7/3.5 = 2
tan θ= 2.0000
θ = 63o
Use mathematical table to evaluate (cos40° - sin30°)
-0.2660
-0.0266
0.0266
0.2660
1.5320
Correct answer is D
(cos 40° - sin 30°)
= 0.7660 - 0.5
= 0.2660
Which of the sketches above gives a correct method for constructing an angle of 120o at the point P?
I only
II only
III only
I and II only
I, II and III
Correct answer is D
No explanation has been provided for this answer.
20o
30o
35o
40o
50o
Correct answer is E
From the figure < TAB = < BTQ = 40° (alternate segment)
\(\therefore\)< ATB = 180° - (70° + 40°) = 70° (angle on a straight line)
< BTC = \(\frac{40°}{2} = \frac{< BTQ}{2}\)
\(\therefore < BTQ = 40°\)
x° = 180° - (40° + 70° + 20°)
= 50°
In the diagram below, O is the center of the circle if ∠QOR = 290o, find the size ∠QPR
110o
70o
55o
35o
20o
Correct answer is D
360o - 290o = 70o
70/2 = 35o
