The interior angles of a pentagon are 126o, 114o, y, 92o and 83o. Find the value of y.
85o
95o
105o
115o
125o
Correct answer is E
Sum of the angle of a pentagon
= (2 x 5 - 4) x 90
= 540o
126 + 114 + y + 92 + 83 = 540
y = 540 - 415 = 125o
From the diagram above, which of the following is true?
a +b + x =180
a = b + x
a – b = 180 - x
a + b = x + 180
a – b = x - 180.
Correct answer is D
From the diagram, the angles in the triangle are:
(180 - a)°, (180 - b)° and x°.
∴∴ (180 - a) + (180 - b) + x = 180°
360 + x - a - b = 180°
360 - 180 + x = a + b
180 + x = a + b.
