Answer:

The answer to your question is:

x = 18

m∠ABD = 36°

m∠DBC = 54°

Step-by-step explanation:

m∠ABD + m∠DBC = 90°

2x + 3x = 90°

5x = 90°

x = 90/5

x = 18

m∠ABD = 2(18)

= 36°

m∠DBC = 3(18)

= 54°

A right triangle has legs of 5 ft and 6 ft. What is the length of the hypotenuse? _____ ft. A. 7.8 B. 3.3 C. 11.0 D. 1.0

Delicious77 [7]

Answer:

<h2>7.8</h2>

Option A is the correct option.

Step-by-step explanation:

Base (b) = 5 ft

Perpendicular (P) = 6 ft

Hypotenuse (h) = ?

Now,

Using Pythagoras theorem,

${h}^{2} = {p}^{2} + {b}^{2}$

${h}^{2} = {(6)}^{2} + {(5)}^{2}$

${h}^{2} = 36 + 25$

${h}^{2} = 61$

$h = \sqrt{61}$

$h = 7.8 \: ft$

Hope this helps...
