Let the third angle be x.
Sum of the interior angles of a triangle = 180°
42 + 84 + x = 180
126 + x = 180
x = 180 - 126
x = 54°
Hence, the third angle is 54°.
Answer:
A
Step-by-step explanation:
y-1=3-1/-2-5 (x-5)
2x+7y=17
The answer is 118 cm³
The volume of tetrahedron (V), where a is its altitude, can be expressed as:
≈ 118 cm³
AC and AB are tangents to circle O, meaning that the angles C and B are right angles of 90 degrees. Since a quadrilateral's internal angles must sum up to 360 degrees, this means that A + B + C + O = 360
70 + 90 + 90 + O = 360
O = 110 degrees.
