Answer:
y = 3
Step-by-step explanation:
Sides MQ and PQ have the same length, so:
12y + 7 = 43
12y = 36
y = 3
Answer:
-0.3110625
Step-by-step explanation:
-0.21*(-2.37) = 0.4977
0.4977*-.625 = 0.3110625
Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
Step-by-step explanation:
arc length for QT = 2× 71° = 142°
