5(14-2)^2/2
5( 12)^2/2
Do the exponent
5(12*12)/2
5(144)/2
144/2= 72
72*5= 360
Answer : 360
Answer:
C
Step-by-step explanation:
the angle in a semicircle = 90° , that is the 3rd angle in the triangle.
the sum of the 3 angles in a triangle = 180° , then
p + 90° + 42° = 180°
p + 132° = 180° ( subtract 142° from both sides )
p = 48°
is the answer.
