Tammy is mountain climbing with Nicole and just climbed an 8 meter rock face Nicole is standing 8 meters away from the bottom cliff looking up at Tammy . How far away are Tammy and Nicole

  8√2 ≈ 11.31 meters

Step-by-step explanation:

The straight-line distance is the hypotenuse of an isosceles right triangle with legs 8 meters. So, the distance is 8√2 meters, about 11.31 meters.

Of course, you know that a right triangle with legs 1 and 1 has a hypotenuse of  ...

  √(1² +1²) = √2 . . . . . given by the Pythagorean theorem

Scaling this by a factor of 8 meters gives you legs of 8 meters and a hypotenuse of 8√2 meters.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
