angle 1 + angle 2 = 90
71 + x = 90
x = 90-7=19
therfore angle 2 is 19
77. The sum of the three angles in a triangle equal the sum of 180 degrees
They are both acute angles because they are less than 90 degrees and the 3rd angle is 71 degrees which is also an acute. The triangle is a scalene triangle.
Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.
i think it is 71 . i think because you can add 62+47 =109-180 so put it like this 108 -109=71
90 - 71 ie 19o
180 - 101 = 79 degrees.
19 Complementary angles add up to be 90 degrees. so, 90-71=19
Complementary angle = 90 - 71 = 19 degrees
Its complementary angle is 19 degrees because 71+19 = 90 degrees
pi*71/180 radians
The sum of the interior angles of a triangle add up to 180o. So 180 - (45 + 71) = 64o
Complementary angle is 71 degrees and supplementary angle is 161 degrees
If the first two angles of a triangle are 45 degrees and 71 degrees then the 3rd angle is 64 degrees.
77. The sum of the three angles in a triangle equal the sum of 180 degrees
They are both acute angles because they are less than 90 degrees and the 3rd angle is 71 degrees which is also an acute. The triangle is a scalene triangle.
Each of the base angles measure 71 degrees
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
