Answer: 7cm
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of the 3 sides together. Let the third side be x , then
x + 9 + 6 = 22
x + 15 = 22
Subtract 15 from both sides , that is
x = 22 - 15
x = 7
Therefore : the third side is 7cm
Answer:
A. x=√60
Step-by-step explanation:
Divide 4 in half because you are solving half of an isosceles triangle
You formula is x²+2²=8²
Square root what you can: x²+4=64
Isolate the variable: x²=60
Square root both sides, x=√60
Answer:
See solution below.
Step-by-step explanation:
Wouldnt that be 2+5 ?? if x is 2 it’s simple, just add them and you get 7.
I think the answer is letter c
