A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
Triangle ABC has angle measures of mA 30 degrees mB 70 degrees and mC 80 degrees What is the measure of the exterior angle at C?
100 degrees
Three angles of a quadrilateral measure 80 100 and 55 degrees what is the measure of the fourth angle?
125°
Interior angle of a convex quadrilateral?
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
What If a triangle has angles whose measures are 55 and 80 what is the measure of the third angle?
The 3rd angle is: 180-55-80 = 45 degrees
What is the complement of the supplement of 80?
The question asks for the complement of (the supplement of (80 degrees) ). We have to find the supplement of 80 first, and then find the complement of the supplement. The supplement of an angle is (180 - the angle). The complement of an angle is (90 - the angle). The supplement of 80 degrees is (180 - 80) = 100 degrees. The complement of that supplement is (90 - 100) = -10 degrees.
What is the measurement of an angle that is 10 degrees complement?
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
What is a complement of an eightty degree angle?
Complementary angles add up to equal 90 degrees. If one angle is already known to be 80 degrees, the remaining complement to the angle would be 10 degrees.
What is the measure of the angle that is complementary to 80 degrees?
90 - 80 = 10 degrees.
Three angles of a quadrilateral measure 80 degrees 100 degrees and 55 degrees what is the measure of the fourth angle?
80 degree
What kind of angle is an angle with a measure of 80?
80 degrees is an acute angle because it is greater than 0 but less than 90 degrees
What is a complement of an eighty degree angle?
complementary angles are defined as 90 degrees - the given angle so 90-80=10 10 degree angle is complementary to an 80 degree angle
What is the measure of the vertex angle of an isosceles triangle if one of its base angle measure 50?
80 degrees
If three angles of a quadrilateral measure 80 degrees 120 degrees and 65 degrees what is the fourth angle?
It is: 360-80-120-65 = 95 degrees which is the 4th angle
What is the angle complement to eighty degrees?
A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
What angle is complementary to an eighty degree angle?
Two angles are complementary of they both add up to 90 degrees. Therefore the complement of eighty degrees would be 10 degrees. (80+10=90)
