ADRE 2024 • 2024 Paper 2Question 1
The two angles of a triangle are 75° and 65°. Twice the measure of its third angle is
A.40°
B.50°
C.60°
D.80° ✓ (Correct)
Explanation: Third angle = $180^\circ - (75^\circ + 65^\circ) = 180^\circ - 140^\circ = 40^\circ$. Twice the third angle = $2 \times 40^\circ = 80^\circ$[cite: 3].
ADRE 2024 • 2024 Paper 2Question 2
If one of the angles of a right-angled triangle is 35°, then which of the following represents an angle of the triangle?
A.40°
B.45°
C.50°
D.55° ✓ (Correct)
Explanation: In a right triangle, one angle is 90°. The third angle = $180^\circ - 90^\circ - 35^\circ = 55^\circ$[cite: 3].
