Answer:
A D E
Step-by-step explanation:
the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)
x + 4x - 85 = 90 Solve this to find the other 2 correct statements
5x - 85 = 90 Add 85 to both sides.
5x = 90 + 85 Combine
5x = 175 Divide by 5
5x/5 = 175/5
x = 35
Since ABD is a single x, that statement (D) is true.
4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well
To find the area of the triangle, use the area of a triangle formula: Area= 1/2(base)(height). In this image, the base of the triangle is 5.9. The height is 6.8. To find this, you multiply 1/2*6.8*5.9 which will give you answer: 20.06
