55 ft
180 degrees -- a straight angle
90 degrees
Yes because it is greater than 0 but less than 90 degrees which makes 50 degrees an acute angle
Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.
No, they can have any angle that makes them add up to 90 degrees, but if it's a bisected complimentary angles then it does have 45 degrees.
A tree broken over by storm forms a right triangle with the ground. If the broken part makes an angle 50o with the ground and if the top of the tree is now 20 ft from its base, how tall was the tree?
180 degrees -- a straight angle
A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees
Are you talking about a reflex angle; an angle that has a larger number degrees than 180.
90 degrees
A total of 90 degrees makes up a right angle.
An angle must be over 90 degrees to be obtuse.
90 degrees
It is: 25*cosine(65) = 10.565 feet rounded
Yes because it is greater than 0 but less than 90 degrees which makes 50 degrees an acute angle
Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.
If it is less than 90 degrees.
