Answer:
Solution given:
<A=49°
<B=90°
angle ECD=?
we have
<A+<B+<C=180°[sum of interior angle of a triangle is 180°
<A+40+90=180°
<A=180°-130°
<A=50°
wehave
<A=<ECD[vertically opposite angle]

Answer:
15 m
Step-by-step explanation:
The area of the square attached to the third side is the sum of the areas of the other squares:
81 m² +144 m² = 225 m²
The side length is the square root of this:
? m = √(225 m²) = 15 m
The length of the indicated side is 15 m.
Answer:
$32
