If it's a right angle triangle then side ac is 10 units in length.
yes
The difference between two sides of a triangle will always be less than the third side.Let ABC be a triangle where AC > AB, extend side AB to point D so that AD = AB + (AC-AB) = AC. Therefore, since AC = AD, triangle ADC is a isosceles where angles ADC and ACD are equal.In the triangle BCD, angle BCD < BDC, Since, angles BCD is part of angle ACD (ACB + BCD ) and angle ACD is equal to BDC .Therefore, using the knowledge that, in a triangle, side opposite a greater angle is always greater than the side opposite a smaller angle, it is proved that, the difference between two sides is always lesser than the third side.In an isosceles, the difference of two sides is zero, since the sides are equal. The third side would always be greater than zero to form a triangle. The same logic can be applied to an equilateral triangle.
If AC equals 6 and BD equals 4, then AB equals 5.
If these are sides of a triangle then AC can have any value in the interval (3, 13).
Remote interior angles are the two angles of a triangle that are not adjacent to the exterior angle which is drawn by extending one of the sides. So when you draw out your triangle, the remote interior angles are the two angles that are the furthest away from your exerior angle.

yes
AB + AC + BC = 48 AB + (AB +9) + (AB + 9 + 3) = 48 Solve and AB = 9 So AB = 9, AC = 18 and BC = 21
149
If ab and ac are each as long as bc then the triangle is, in fact, equilateral, not just isosceles. Therefore, each side is 20/3 cm = 6.66... recurring cm.
In right triangle ABC, angle C is a right angle, AB = 13and BC = 5 What is the length of AC? Draw the triangle to help visualize the problem.

Not too sure about the question as there is no triangle pictured at the right. But in general the area of a triangle is 0.5*base*perpendicular height
By using Pythagoras' theorem for a right angle triangle if side AB is the hypotenuse it is the square root of 149 which is about 12.207 rounded to three decimal places
If CB is the hypotenuse, then AB measures, √ (62 - 52) = √ 11 = 3.3166 (4dp) If AB is the hypotenuse then it measures, √ (62 + 52) = √ 61 = 7.8102 (4dp)
