It is a right angle triangle because the 3rd angle is 90 degrees
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
55 degrees because there are 180 degrees in a triangle
The sum of two complements is 90 degrees, or a right angle. 90-35=55 degrees.
A pair of complementary angles sum up to 90 degrees. In this instance, the complement of a 55-degree angle is 90 - 55 = 35 degrees.
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees
55 degrees
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
The complement of 35 degrees is 55 degrees, since they add up to 90 degrees.
The triangle with angles measuring 55 degrees, 70 degrees, and 55 degrees is an isosceles triangle. This is because it has two angles that are equal (the two 55-degree angles), which also means the sides opposite those angles are of equal length. Additionally, since the sum of the angles equals 180 degrees, this confirms it is a valid triangle.
A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
Since all the angles in a right triangle add up to 180 and we already have 145, this means that the third angle must be 35 degrees.
55 degrees.
They are 55 degrees and 66 degrees respectively
