Are u solving for x or y?
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²
Answer:
30, assuming it's a right triangle
Step-by-step explanation:
The answer assumes this is a right triangle. Otherwise, it's impossible to answer.
The sum of angles in a triangle is 180deg. As we know 2 of the angles (90deg and 60deg) we need to subtract them from 180deg.
180-90-60 = 30
