Answer:
71: 19 72: 100 73:9 74:1 75:-2 76:4
Step-by-step explanation:
71. 2(12)-5 = 24-5 = 19
72. 2(5(12)-10) = 2(60-10) = 2(50) =100
73. 3+12/2 = 3+6 = 9
74. 4(5)/12+4(2)= 20/20 = 1
75. 2(2)^2-10 = 8-10 = -2
76. 12-10+2 =4
Answer: The third One
C. 253.5
∠ XYZ ≈ 72.9°
Using the tangent ratio in the right triangle
tanXYZ = = = , thus
XYZ = ( ) ≈ 72.9° to 1 dec. place )
