Answer:
[see below]
Step-by-step explanation:
Use the Pythagorean Theorem.
'c' will be the hypotenuse.
The hypotenuse is 15 cm. One of the legs is 5 cm.
14.1421356237 ≈ 14.1
The other leg should be about 14.1 cm.
Hope this helps.
Since the tangent of B is 4/3, then:
On the other hand, since ABC is a right triangle with hypotenuse BC, then:
Substitute AC=3/4 BA and BC=15 to find BA:
Substitute BA=12 into the expression for AC to find its value:
On the other hand, we know that:
Substitute BA=12 and DA=3 to find BD:
Finally, since BDE and BAC are similar triangles, we know that:
Substitute AC=12, BA=9 and BD=6 to find the length DE:
Therefore, the length of DE is:
