How do you know if a triangle is right angled if the hypotenuse measurement is not given?

You should be able to see the right angle - 90 degrees


A triangle Has an angle measuring 35 degrees and another measuring 43 what is the measurement of the missing angle?

In a triangle, the sum of all three angles is always 180 degrees. Given that one angle measures 35 degrees and another measures 43 degrees, you can find the missing angle by subtracting the sum of these two angles from 180 degrees. Therefore, the missing angle is 180 - (35 + 43) = 102 degrees.


In the figure angle E measures 30 and deg angle F measures 57 and deg and angle B measures 27 and deg. What is the measurement of angle A?

To find the measurement of angle A in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Given that angle E measures 30 degrees, angle F measures 57 degrees, and angle B measures 27 degrees, we can calculate angle A as follows: Angle A = 180 - (angle E + angle F + angle B) = 180 - (30 + 57 + 27) = 180 - 114 = 66 degrees. Therefore, angle A measures 66 degrees.


How many triangles exist with the given angle measures degrees 45 degrees and 90 degrees?

As many as you like because any triangle that has a 90 degree angle is always a right angle triangle.

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.

What is the cos of angle a 5 13 12?

It is: cos = adj/hyp and the acute angles for the given right angle triangle are 67.38 degrees and 22.62 degrees


What is the third angle of a triangle with two angles given as 54 degrees and 62 degrees?

The sum of a triangle's angles must always equal 180, so 54+62=116. 180-116=64. The third angle is a 64 degree angle.
