Answer:
Where-
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
use formula a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
- 144 -144
a^2 = 25
sqrt sqrt
a = sqrt (25)
a = 5
Answer:
84 m²
Step-by-step explanation:
A= h(a+b)/2 = 7(8+16)/2 = 84
it would be adding by 2's because to get from 2 to 4 you have to add two or from 6 to 8 you have to add two also
