Answer:
x = 4
CB = 28
Step-by-step explanation:
In triangle ABC,
AB = CB..... (given)
Therefore,
7x = 5x + 8
7x - 5x = 8
2x = 8
x = 8/2
x = 4
CB = 5x + 8 = 5*4 + 8 = 20 + 8 = 28
Answer:
y = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
y² = 8² + 4² = 64 + 16 = 80 ( take the square root of both sides )
y = = = 4 ← exact value
Solve, for the first variable in one of the equation, the substitute the final result into the other equation
