Given that the isosceles triangle has sides √45, √45 and x.
The triangle has a height of 3 units.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the formula,
Where b is the base of the triangle, a is the sides of the isosceles triangle and h is the height of the triangle.
Substituting , and in the above formula, we get;
Squaring the terms, we have;
Subtracting, we get;
Thus, the value of x is 12
Hence, Option B is the correct answer.
Answer:
85 square ft
Step-by-step explanation:
8.5cm times 4 cm = 34 cm
34 cm times 2.5 (because 1 cm = 2.5ft) = 85 square ft
6/5 because you add 1.5 to both sides, the. Add 2 to both sides, then divide to get a by itself

4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.
