Answer:

Step-by-step explanation:
Angles in a triangle add up to 180
An acute angle is any angle smaller than 90
Since it is a right angle triangle, one of the angles is a right angle and therefore 90
So 180 - 90 - 25 = 65
Answer:
SA = 153.9m^2
Step-by-step explanation:
SA = 4

r = 3.5
SA = 4

SA = 4
(12.25)
SA = 49
SA = 153.9m^2
3 is the largest number that will go into both 81 and 60
