Answer:
50
Step-by-step explanation:
Use pythagoreom theorem to determine the length of the hypotenuse:
a² + b² = c²
- assign side a to 30 and side b to 40
30² + 40² = c²
90 + 160 = c²
250 = c²
Now square root both sides to isolate side c:
√250 = √c²
50 = c
side c = 50
Answer:
2 and 1/4
Step-by-step explanation:
3/4 + b = 3
rearrange the equation
3 - 3/4 = b
3/1 - 3/4 = 14/4 - 3/4 = 11/4 = 2 and 1/4
Answer:
5/6
Step-by-step explanation:
Rectangle Formula: a = lw (Area = Length x Width)
Trapezium: A= a+b/2h (Area = Area + Base / 2 x h)
I hope this helps. :)
