A^2 + b^2 = c^2
9^2 + b^2 = 12^2
81 +b^2 = 144
-81 (subtract 81 from both sides of the equation)
b^2 = 63
b = square root of 63
Answer:
Length of each leg = 130 cm.
Step-by-step explanation:
Given that there is an isosceles triangle which has perimeter 345 cm.
Base length =85 cm.
Since other two sides are equal, let the equal size = x
Perimeter = sum of all 3 sides of a triangle
= 85+x+x = 85+2x
But perimeter = 345 (given)
So equate x term perimeter with actual
85+2x = 345
Subtract 85
2x = 260
Divide by 2
x =130 cm.
Hence answer is 130 cm.
Answer:
are those other numbers negative or is that what you are using to separate them? because if they are negative I would say #1 because it's the only positive one
Answer:
B
Step-by-step explanation:
Solve each inequality separately
2x + 3 ≥ 7 ( subtract 3 from both sides )
2x ≥ 4 ( divide both sides by 2 )
x ≥ 2
or
2x + 9 > 11 ( subtract 9 from both sides )
2x > 2 ( divide both sides by 2 )
x > 1
x ≥ 2 satisfies the condition for both inequalities
Thus x ≥ 2 is the solution
