What are the other two angles and its 3rd side of a triangle having an angle of 48 degrees opposite to side 15.3 cm with an adjacent RHS of 17.6 cm?

Let the angles be A B C and their opposite sides be a b c and so:-
Angle A = 48 degrees
Using the sine rule angle B = 58.7 degrees
Angle C: 180-468-58.7 = 73.7 degrees
Using the sine rule side c = 19.7 cm
Alternatively: 180-58,7 = 121.3 which then is angle B and so:-
Angle A = 48 degrees
Angle B = 121.3 degrees
Angle C: 180-48-121.3 = 10.7 degrees
Using the sine rule side c is now 3.8 cm

In a right triangle the ratio of the opposite side to the adjacent side?
In a right triangle, two of the angles are acute ones. Referring to one of the acute angles, the ratio of the side opposite it to the side adjacent to it is the tangent of the angle.
Is there such thing as a right angled triangle?
Yes, there is such thing as a right-angled triangle. The measure of the adjacent and opposite form together to create a 90 degree angle. That means that the measure of the hypotenuse and adjacent must be 45 degrees and the hypotenuse and opposite measures to 45 degrees.
What is the side adjacent to the forty degrees of a right triangle has a hypotenuse of 6 meters and one of its angles measure forty degrees?
The side adjacent to the forty degrees of a right triangle with a hypotenuse of 6 meters and one of its angles measuring forty degrees is: 4.6 meters.
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
What shape has no right angles adjacent sides the same length?
an equilateral triangle (all sides are adjacent and 60 degrees)
What is the tangent of a triangle?
In that triangle, one of the angles must be a right angle, and another one of the angles must be marked with or the measurement of the angle. Tangent is the ratio of opposite side over adjacent side. The opposite and adjacent sides are determined by the position of the marked angle.
The nonadjacent angles formed by two intersecting lines?
two adjacent angles formed by two intersecting tines are
In a parallelogram with angles LMNO where L equals 32 degrees what does the adjacent angle O equal?
For angle L, the adjacent angle o, and its opposite angle M, are both 158 degrees. (it's a rhomboid) In a parallelogram, adjacent angles total 180 degrees (they are supplementary), since the opposite angles must be the same and there are two of each.
Exterior angle of a triangle is sum of the?
The exterior angles of a triangle add up to 360 degrees.
What is the equation for finding the sine and cosine and tangent of a triangle?
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
What are the 4 degree numbers on a rhombus?
Suppose on of the angles is A degrees where 0 < A < 90. Then the opposite angle is also A degrees and the two adjacent angles are (180 - A) degrees.
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
