In \(sin(X+30)^o=cos40^o\),find X
10o
20o
50o
60o
90o
Correct answer is B
\(sin(X+30)^o=cos40^o\\
X+30+40=90^o\)complementary angles
\(X=20^o\)
In the diagram, PQ||SR. Find the value of Z
30o
40o
45o
90o
120o
Correct answer is D
Given PQ//SR
x = 45º
y = 45º
z = ?
Sum of angles in a triangle = 180º
(x + y + z)º = 180º
(45 + 45 + z)º = 180º
90º + zº = 180º
z = (180 - 90)º
z = 90º
