Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
ABC angle is an angle,not a triangle!
triangle ABC with rigth at C
The sum of the two angles is 360. So angle ABC = 120 degrees.
.
Angle abc will form a right angle if and only if, segment ab is perpendicular to segment bc.
Yes, so as long as the angle being identified (in this case, angle b) is in the center.
50
Angle abc.
The vertex of the angle.
To have a congruent angle, the measure of the two angle must be the same, so if ABC is 15 degrees, then FDE would have to be 15 degrees also to be congruent.
Angle ABD = 4x - 4 Angle ABC = twice angle ABD = 7x + 4 So 7x + 4 = 2*(4x - 4) = 8x - 8 So x = 12 Then angle DBC = half of angle ABC = 1/2*(7*12 + 4) = 1/2*88 = 44 degrees.
