The side opposite the angle 19 degrees is given by 15sin 19 = 4.9 units, while the side adjacent the angle 19 degrees is given by 15cos 19 = 14.2 units. So answer = 4.9 units, 14.2 units.

How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?
By using trigonometry that is applicable to a right angle triangle.
Can an equilateral triangle be acute?
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
What is HA Congruence Theorem?
HA Congruence Theorem says: If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two right triangles are congruent.
Which type of triangle has three angles with measures less than 90°?
A triangle which measures less than 90%
What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
What is degree of hypotenuse?
A triangle with an hypotenuse has a right angle that measures 90 degrees and two other acute angles,
How do you find the short leg of a right triangle?
The answer depends on what information you do have about the triangle: the lengths of the other two sides, or the hypotenuse (longest side) and one of the acute angles, or the other leg and one of the acute angles, etc.
In the figure, all congruent segments are marked as congruent.Classify the triangle by its side lengths and angle measures?
equilateral acute
How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?
By using trigonometry that is applicable to a right angle triangle.
The hypotenuse of a right triangle is the opposite side acute?
Angles are acute, not sides.
Can an equilateral triangle be acute?
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
What are the properties of a right-angle triangle?
A right triangle has one right angle and two acute angles. Right triangles have a hypotenuse and also two legs. You can use the Pythagorean Theorem to find the hypotenuse, or the two legs of the right triangle, as long as you have the side lengths of the other two sides on the right triangle.
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
What is the sum of the measures of the three angles of an acute triangle?
The sume of the measures of the three nagles of an acute triangle (or any triangle) is 180 degrees.
What side lengths makes a triangle acute?
An acute triangle sometimes known as a scalene triangle has 3 different side lengths and 3 different interior acute angles that add up to 180 degrees
What does the hypotenuse-angle theorem say?
If the hypotenuse and an acute angle of a right triangle are congruent to the correspondingparts of another right triangle, then the triangles are congruent.
What is an acute triangle called?
A triangle with 3 different interior acute angles is a scalene triangle and its 3 sides will be of different lengths
