Step-by-step explanation:
You might be wondering how did I got 32⁰, well, that's because they are alternate angles.
Now, we're trying to find the opposite side of the triangle.
Using the laws,
we got cos32⁰=x/243.8
243.8cos32⁰=x

Answer:
141
Step-by-step explanation:
Area of a trapezium = (a + b)
h = height
a and b = upper and and lower lengths
Area of a trapezium = (10 + 16)
= × 26
= 117
Area of a triangle = × base × height
= × 6 × 8
= × 48
= 24
Total area = Sum of the areas of both the shapes
= 117 + 24
= 141
