Answer:
-13/30
Step-by-step explanation:
take 1/6 to other side,
x=-3/5 -1/6
taking LCM of denominators,
-8-5/30
=-13/30
Answer:
x = 58°
Step-by-step explanation:
ABCD is a cyclic quadrilateral and opposite angles are supplementary , so
∠ DAB = 180° - 121° = 59°
The angle between a tangent and a chord is equal to the angle in the alternate segment, then
∠ ABD = 63° , thus
x = 180° - (59 + 63)° = 180° - 122° = 58°
Answer:
It is isosceles by the base angles theorem. It states that when the base angles are equal, the triangle is isosceles.
