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.
Two eggs serve three people, and to get 15 people you multiply by five, so you multiply two eggs by five giving you ten eggs. You'll need 10 eggs to serve 15 people.
Step-by-step explanation:
(3*4+1) / 4. * (2*5+3) / 5
= 13/ 4 * 13 /5
= 169/20
Answer:
2, 4, and 6
Step-by-step explanation:
Supplementary angles are angles that add to 180°.
We can see that the angles that make a straight line/straight angle with ∠7 are supplementary to it, because a straight line is 180°.
Those numbers would be be 2, which equals to 4, which equals to 6 and also 8, but that number isn't one of the answers
2,4, and 6
