Surface area of this triangular prism is
Area of 2 congruent triangles + Area of rectangle(6*2) + Area of rectangle(2*4) + + Area of rectangle (2*3)
Area of triangle = 1/2*6*2 =6 in²
Surface area of this triangular prism = 2*6 +6*2 +2*4 +2*3= 12+12+8+6= 38 in²
Answer is 38 in².
Answer:
70°
Step-by-step explanation:
Size of angle a = (180°-40°) ÷ 2 (angle sum of triangle; base angles of isos triangle)
= 140° ÷ 2
= 70°
Answer:
Choice C: (x-2)^2 + (y-1)^2 = 25
