180 degrees in a triangle
180-70-30 = 80
The other angle is 80 degrees
A Square Or A Quadrilateral Or A Polygon With Four Straight Sides Has 360 Degrees!!=] I Know This Is Not The Question But It Is Related] A Triangle Has 180 Degrees!!=)
There are four types of triangles. For an "equilateral triangle", all sides and angles have to be the same. For an "isosceles triangle", 2 of 3 sides and angles have to be the same. For a "scalene triangle", the "the same" rules don't apply. For a "right-angled triangle", one corner has to be a right angle (90 degrees.) For example in an equilateral triangle, as long as the sides are the same, they can add up to anything. However, angles are different. In any given triangle, the angles must add up to 180 degrees.
you work out how much it is to 180
what is the measurement of an acute angle
Every triangle has three angles that total 180o. In an equilateral triangle, there are three 60o angles.
Regardless of whether the "other measurement" is an angle or the length of something, that much information is never enough to define anything else about the triangle.
The inner angles of a triangle add up to 180 degrees. 180 - (70 + 30) = 80 degrees.
The angles of a triangle always add up to 180o. A right angle triangle has angle of 90o, 60o, 60o.
easy a triangle makes up a total of 180 degrees so add the two up and then see how much more is needed for 180 and there's your answer
To find all the other information of a triangle, you would need the information of an SAS (Side Angle Side, in that order), an ASA (Angle Side Angle), or a SSS (Side Side Side). Only triangles shown with this much information can be solved, other than that, you just can't be sure of the rest of the measures of the sides and angles.
Al you need to get is a protractor to measure it really. say you had a straight line you know how much that measures and you know how much the other angle measures so subtract it and you have the answer!
There could be almost any acute angle. it maters what kind it is
It depends on the triangle, whether it's an isoscelese, scalene, equlateral, obtuse, right angle or acute triangle. All the angles have to add up to 180 degres no matter what, so a right angle triangle could be 90, 45 and 45.
180 degrees. An equilateral triangle measures 60 degrees at every angle.
Total, the triangle has 180 degrees, and each angle has 60 degrees.
A triangle always has three sides, thus the name tri-angle (3 angles)
An acute triangle can have as much as 3 acute angles providing that they all add up to 180 degrees.
