Answer:
x ≈ 6.2 cm
Step-by-step explanation:
using the cosine ratio in the right triangle
cosΘ = , that is
cos39° = =
( multiply both sides by 8 )
8 × cos39° = x , then
x ≈ 6.2 cm ( to 1 dec. place )
Answer:
<u>The true statements are:</u>
1) The equation a squared + (√13) squared = 6 squared can be used to find the unknown length.
2) The length of the unknown leg is √23 meters.
=================================================
Step-by-step explanation:
The hypotenuse of the right triangle = 6
And the length of one leg is √13
using Pythagorean equation: c² = a² + b²
where c is the hypotenuse and a , b are the length of the two legs
So, the third side =
<u>So, the true statements are:</u>
1) The equation a squared + (√13) squared = 6 squared can be used to find the unknown length.
2) The length of the unknown leg is √23 meters.
