Answer:
x = 2√2
Step-by-step explanation:
Since the triangle is isosceles, it means 2 of the angles are equal and 2 of the sides are also equal.
Now, since we see that it is also a right angled triangle, it means one angle is 90°.
Let the equal angles be a.
Thus;
a + a + 90 = 180 (since sum of angles in a triangle is 180)
2a + 90 = 180
2a = 180 - 90
2a = 90
a = 90/2
a = 45°
Now, using sine rule, we can find x. Thus;
x/sin 45 = 4/sin 90
sin 90 = 1
sin 45 = 1/√2
Thus;
x = (4 × 1/√2)/1
x = 4/√2
Let's rationalize the denominator to get;
x = (4/√2) × √2/√2
x = (4√2)/2
x = 2√2
Answer:
Square root (V) of 150:
5 V6 (5*Square root of 6)
Square Root (V) of 7/2
V14/2 (square root of 14)/2
A product is zero if and only if at least one of the two factors is zero. So, you need either
or
In the first case, the equation reduces to
In the second case, we have
So, you need one of the following three to happen:
I assume you have a table to look up for these known values. If you have trouble solving for
