Find the measures of the angles of a triangle if the measures of one angle is twice the measure of a second angle and the third angle measures 3 times the second angle decreased by 12?
Let the second angle of the triangle be A. Then angle 1 = 2A : and angle 3 = 3A - 12 The internal angles of a triangle total 180° therefore :- 2A + A + (3A - 12) = 180 6A - 12 = 180 : 6A = 192 : A = 32 The angles measure 64° , 32° and 84° .
How do you find the volume of a 90 degree wedge?
First find the are of the 90 degree triangular end. This is 0.5*a*b where a and b are the two legs of the triangle adjacent to the right angle. Multiply the result by the length of the wedge.

How would you find out the sin tan and cos of right angle triangle?
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.

How can you find a missing side or angle of a right triangle?
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
What if The second angle of a triangle is 20 degrees greater than the first angle. The third is twice the second. Find the three angles.?
Angle 1 = 30 degrees Angle 2 = 50 degrees Angle 3 = 100 degrees.
The second angle of a triangle is four times as large as the first The third angle is 10 degrees more than three times the first angle Find the measure of the first angle?
Let x equal the first angle.let 4x= the second anglelet 3x+10x+4x+3x+10=180 The sum of the interior angle measures of a triangle is 180 degrees.8x+10=180 combine like terms8x=170 addition(subtraction) property of equalityx=21.25 degrees

How do you find the third interior angle of a triangle?
Add the first two angles together and subtract the total from 180 to find the 3rd angle
How do you find the angle of a an right triangle?
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
The measure of the second angle in a triangle is five less than the first. The third angle is thirteen more than twice the first. Find the measure of each angle?
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
The second angle in a triangle is four times as large as the first The measure of the third angle is 80 degrees more than sum of the other two angles. Find the measure of the second angle?
Let the first angle be x the second angle be 4x and the third angle be 80+4x+x: x+4x+80+4x+x = 180 Collect like terms: 10x = 180-80 10x = 100 x = 10 Therefore the measure of the second angle is 40 degrees.

What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
