4 0

Answer:

x = 27

Step-by-step explanation:

30 \degree =  \frac{1}{2}  \{(5x + 10) \degree - (3x + 4) \degree \} \\ 30 \degree  \times 2=    \{(2x + 6) \degree \} \\ 60 \degree  =    (2x + 6) \degree \\ 60   =    2x + 6 \\ 2x = 60 - 6 \\ 2x = 54 \\ x =  \frac{54}{2}   \\  \huge \red { \boxed{x = 27}} \\

Which side lengths form a right triangle?<br> Choose all answers that apply:
kkurt [141]

Answer:

All 3 are right triangles.

Step-by-step explanation:

In a right triangle c^2 = a^2 + b^2   where c is the longest side.  ( by Pythagoras).

a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27

36 = 9 + 27

So this is a right triangle.

b)

17^2 = 289, 15^2 = 225 and 8^2 = 64

289 = 225 + 64

Also right triangle.

c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25

So also right triangle.

What is the inverse function of d(x) = 2x - 4?
Naddik [55]
Let d(x) = 2x - 4

Or

y = 2x - 4

We have replace x = y

x = 2y - 4

Now Isolate "y"

x + 4 = 2y

Pass "2" dividing

(x + 4) / 2 = y

y = x/2 + 2

Or

d(x)^-1 = x/2 + 2
