Answer:
The perimeter is 66.9 units
Step-by-step explanation:
See the attached figure with letters to better understand the problem
step 1
In the right triangle ABD
<em>Find the length side AD</em>
----> by TOA (opposite side divided by the adjacent side)

Find the length side BD
---> by SOH (opposite side divided by the hypotenuse)

step 2
In the right triangle CDE
Find the length side CE
--> by CAH (adjacent side divided by the hypotenuse)
we have

substitute

Find the length side DE
--> by TOA (opposite side divided by the adjacent side)

step 3
Find the perimeter of the figure
The perimeter is equal to

substitute the values

4,540,000 in scientific notation is 4.54 x 10^6
Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
Answer:
D. 73°
Step-by-step explanation:
The inside angles of a triangle always equal 180° so if we know that a right angle is already 90° we only need one more angle to know all of them:
1. 90° + 17° + ?° = 180
2. 90° + 17° = 107°
3. 180° - 107° = 73°
4. 90° + 17° + 73° = 180
