Try by dividing this shape into three different squares then find the area of each shape then add them together.
When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
1) Square all 3 sides.
4, 3, 4,
16, 9, 16
2) Sum the squares of the 2 shortest sides.
16 + 9 = 25
3) Compare this sum to the square of the 3rd side.
25 > 16
if sum > 3rd side² Acute Triangle
So, it is an acute triangle.

Im assuming the height is dropped so that it is the halfway point. this would then make the base 5cm, with a height of 12cm. if that is the case then the answer should be 13
-5 + x = +
adding/subtracting numbers with same/different signs : if the signs are the same, whether both negative or positive, then the answer will contain the same sign.
Example : -2 + (-2) = -2-2 = -4 : both signs are negative, the sign stays negative.
5 + 5 = 10 : both signs are positive, the sign stays positive.
However, if the signs are different, u subtract the smallest number from the largest number and take the sign of the larger number.
Example : -2 + 5 = 3...I took 5 - 2..which is 3, and took the sign of the largest number (+)...so the answer is 3.
-5 + 2 = -3....I took 5 - 2 and got 3, but used the larger number sign (-) making the answer -3.
now for ur question....u can conclude that the sign of the other integer would have to be positive. As for the value, in order for the answer to be positive, the integer would have to be larger then + 5.
Example :
-5 + 6 = 1
-5 + 7 = 2
if u picked a positive number smaller then 5...
-5 + 4 = -1
-5 + 3 = -2
u would not get a positive result.
