50 o

Explanation:

The sum of the measure of the internal angles of any triangle is  

180 o .

In a right angled triangle, one angle will be  90 o .

Since we know the measure of one of the other acute (less than  90 o ) angles, we subtract the sum of the two known angles from  180  to calculate the measure of the other acute angle.

180 − ( 90 + 40 )

180 − 130

50

Answer:

25 and 65

Step-by-step explanation:

U have established that this is a right angled triangle, so:

180- 90 = 90

an acute angle is 30 degrees or less

meaning that your answer must sum up to 90 and one of the numbers should be 30 or less
