A triangle has one angle of 80 degrees and another of 60 degrees how manydegrees must there be in the third angle?
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
A triangle has one angle 80 degrees and another of 60 degrees how many degrees must there be in the third angle?
40 degrees
What is the third angle of a triangle that has 80degrees and 40 degrees?
Triangles have three sides that sum up to 180°.You are given two sides, 80° and 40°, and need to solve for the third side.First make an equation, then plug in the two given sides to any of the two variables.A + B + C = 180°80° + 40° + C = 180°Now solve for the remaining variableC =180° - 40°- 80° = 60°The third angle is 60°
A triangle is 80degrees and 60 degrees what is the third angle?
Let's say that the angles of this triangle is supplementary. So our equation will be: 80 + 60 + x = 180 Solve for x (80 + 60) 140 + x = 180 x = 180 - 140 x = 40 That is the measurement of the third angle. To check, just simply add the 3 and you'll get 180 - ericka janolo http://www.friednster.com/ekang03
Do all types of triangle have the same area?
no. even tho that all triangle have 180 degrees fortheir angles it doesnt mean that all the sides of the traingles haveto be the same. you could have a triangle with sides of 100 ft 80 ft and 60 ft and another triangle with 100in 80 in and 60 in. obviously these traingles are going to have different areas.
