Answer:
A: 6 triangles with height 10.4 inches each and base 12 inche
B: 62.4 square inches
C: 374.4 square inches
Step-by-step explanation:
Part A: You can form a triangle by connecting E to the top of the segment and connecting the top of the segment to D. Recreating this with each section will create 6 triangles with height 10.4 inches each and base 12 inches.
Part B: The area of a triangle is A = 1/2b*h. Substitute h = 10.4 and b = 12.
A = 1/2*10.4*12 = 62.4
Part C: There are 6 triangles each with area 62.4. So the area of the whole figure will be 6*62.4 = 374.4.
Area=6x10=60 feet as it is rectangle so all angles are 90° and oppossite sides are equal
You basically just get a equation that needs to be answered and grab the answer and minus it by one of the two digits in front. Example: 3+2=5 is equal to 5-2=3
Answer:
x = 25
Step-by-step explanation:
Assuming Angle A, B and C are angles in a triangle.
∠A + ∠B + ∠C = 180º
(2x - 20) + (120) + (x + 5) = 180
2x - 20 + 120 + x + 5 = 180
3x + 105 = 180
3x = 75
x = 25
