Answer:
4.71cm
Step-by-step explanation:
You draw the reference angle of 45° but clockwise. The exact value of sin(-345°) is 1/√2.
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side (or else, it can't be a closed polygon). Since we know that the two sides in question are both of the same length in this case (since the triangle isosceles), their individual lengths must be greater than 25/2 = 12.5.
Squaring a number means you're multiplying the number by itself. This would mean (6b)^2 = (6b)(6b).
