Step-by-step explanation:
45°, 45°, 90° triangle theorem states that:
Lengths of the sides opposite to the 45° angle are equal to one upon root two times of the length of hypotenuse.
Mathematically it can be expressed as:
The answer is
hope it helps
Answer:
m<1 = 87
m<2 = 45
m<3 = 45
m<4 = 52
if BC intersects <ACD then that means angle 2 and 3 = 90
so that being angle 2 and 3 are the same
now you do 180-(45+48) = 87
now same thing but 180-(45+83) = 52
the answer is
About 50 inches
207$ - 15$ = 192$
192$ : 8 = 24$
Answer: Each book costed 24$.
