Question

two acute anglesof a right angled triangle are equal.find the two angles

Answer 1

acute angle = a= c

where b is 90°

a+b+c=180 { angle sum Property of ∆}

a+a+c=180

2a=90

a=45

a=c=45°

Answer 2

AS WE KNOW THAT THE SUM OF TWO ACUTE ANGLES OF RIGHT ANGLED TRIANGLE=90°

AND WE ALSO KNOW THAT ONE ANGLE OF RIGHT ANGLED TRIANGLE IS EQUAL TO 90°

SO THEN ,OTHER TWO ACUTE ANGLES
WILL BE 45°,45°. √

45°+45° =90°

HENCE,THESE TWO ACUTE ANGLES ARE 45° ,45°.√
