8) 10 m 9) 26 in 10) 51 m 11) 50 ft 12) 19.4 cm 13) 177.9 m 14) 40 15) 12 16) 14.7 17) 12.1
Step-by-step explanation:
You may solve the problems by using the Pythagorean Theorem which states that c^2 = a^2 + b^2, or in other words, the hypotenuse squared is equal to the sum of the legs squared. 
Hope this helps! :-)
 
        
             
        
        
        
Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° =  =
 =  =
 =  ( multiply both sides by 7 )
 ( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )
 
        
             
        
        
        
To solve the given equation, w need to review some rules:

The given equation is :


  ⇒⇒⇒⇒ rule (2)

  ⇒⇒⇒⇒ rule (1) and rule (2)

          ⇒⇒⇒⇒ rule (3)
removing the nature logarithm from both sides

∴ x = 4
So, the correct answer is option (2) ⇒⇒⇒⇒ x = 4

Answer:
3/13
Step-by-step explanation:
First...
What we know
1. There is a set of 13 shapes.
2. With 2 triangles, 8 arrows, and circles.
Next...
Take the number of triangles and arrows and add them up.
2 + 8 = 10
Finally...
Convert it into the fraction 10/13 and subtract it by the total 13/13. 
This results 3/13.
