Arctan(3.4) ≈ 73.6°. You can view the 3.4 as the slope of a line. Then it is clear the the 52.9 and 99.8 can't be right. If you have to do this without a calculator, it can be quite tricky...
Answer:
756 m²
Step-by-step explanation:
The ratio of areas is the square of the ratio of linear dimensions. Hence the area of the red solid is ...
(6/4)²×336 m² = 756 m²
Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15
