Answer choice C is correct
Answer:
y = 9√2
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
y² = 9² + x²
By the property of isosceles triangle,
Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.
Therefore, x = 9
y² = 9² + 9²
y² = 81 + 81
y² = 162
y = √162
y = 9√2
Answer:
360
Step-by-step explanation:
5x10=50
Bottom- 12x10=120
Triangle -5x12=60/2=30
30x2=60
Top- 13x10=130
50+120+60+130=360cm
Since 1 dm=10cm
53.6dm= 536 cm
Thus
536 cm= 536 cm
