Answer:
9 and 11
Step-by-step explanation:
The triangle sum theorem says all 3 interior angles must equal 180 degrees.
so, 43 + 35 = 78. [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.
102 + 18 = 120. [180 - 120 = 60}
leaving the measure of Angle A as 60 degrees.
Area=length * width
You know area and width. Plug in and solve.
24=length*4
Length =6 meters
Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm

= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm
