Step-by-step explanation:
Answer:
x = 10√3
Step-by-step explanation:
Because of the right angles, we can use Pythagoras
30² - x² = y² (a) Largest triangle
y² - 20² = h² (b) Medium triangle
substitute y² from (a) into (b)
30² - x² - 20² = h²
500 - x² = h² (d)
x² - h² = (30 - 20)² (c) smallest triangle
substitute h² from (d) into (c)
x² - (500 - x²) = 100
2x² = 600
x² = 300
x = 10√3
6(21)=72 6(31)=186
add 72+186=258
258 is the answer
Hey!~
The answer is 25/100.
0/100 (0) and 50/100 (1/2) : The middle is 1/4.
Hope this helps and have a great day!
