Answer:
10,
Step-by-step explanation:
The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.
The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200
y = √200 = √100√2=10√2
Answer:
a = 4
Step-by-step explanation:
Let the number be a.
2× a = 8 ...(1)
We need to find the value of a such that th above equation is true.
Divide both sides of equation (1) by 2 .
a = 8/2
a = 4
Hence, if the value of a is 4 the equation will become true.
