Answer:
12.5cm
Step-by-step explanation:
This triangle is either isosceles or equilateral, we already know two sides.
the other side of the triangle is also 5 cm long because it is also the radius of the shape
the format for finding a right angle triangle like this one is base x height / 2
5 x 5 = 25
25/2 = 12.5
12.5 rounded is 13 because the decimal number is 5 and 5 or higher means we need to round up.
hopefully this helped

Answer:
First choice: m = -4
Step-by-step explanation:
The second equation is already solved for n, so lets's use the substitution method and substitute m - 2 for n in the first equation.
m - 2n = 8
m - 2(m - 2) = 8
m - 2m + 4 = 8
-m + 4 = 8
-m = 4
m = -4

Answer:
15/10
Step-by-step explanation:
Since it is adding you need to get a common denominator(bottom number).
I know that 2 × 5 = 10 so now we multiply 3/5 × 2
we get 6/10
now the problem is 9/10 + 6/10
9 + 6 = 15 and the denominator is 10
15/10
