In a right triangle, one angle should be a right angle, which means that angle should be 90°. Right angles are always 90°.
And in any triangle, the sum of the 3 interior angles should add up to 180°, this rule is always the same. Therefore, to find the third angle, we should simply subtract the angles we already know from the angle sum of triangle.
We can therefore list this equation:
Third angle = 180° - 24° - 90°
Third angle = 66°
Your answer should be 66°
Answer:
no then its not a right triangle
Step-by-step explanation:
Train A:
Distance (s) = 420 miles
Time (t) = 3 hours
Speed (v) = distance ÷ time = 420 ÷ 3 = 140 miles/hour
Train B:
Distance (s) = 420 miles
Time (t) = 2.25 hours
Speed (v) = distance ÷ time = 420 ÷ 2.25 = 186.7 miles/hour
