Find the value of x in the following parallelogram x =

iVinArrow [24]

Answer:

$x=60\degree$

Step-by-step explanation:

Consecutive angles of a parallelogram are are supplementay.

$\implies \: x + 2x = 180 \degree \\ \\ \implies \: 3x = 180 \degree \\ \\ \implies \: x = \frac{ 180 \degree }{3} \\ \\ \implies \: x =60 \degree$

If f(x) = 3x - 9 and g(x) = x², what is (gºf)(5)?

Xelga [282]

Answer:

Step-by-step explanation:

Here, f(x) is the input to g(x), forming a composite function.

To evaluate (gºf)(5),

1) find the value of f(5). It is f(5) = 6.

2) Use this result as the input to g(x): g(6) = (6)^2 = 36

Which side lengths form a right triangle

aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

A right triangle consists of two legs and a hypotenuse.
To find hypotenuse, we use The Pythagorean Theorem
The Pythagorean Theorem = ${a}^{2} + {b}^{2} = {c}^{2}$
two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

${5}^{2} + { \sqrt{6} }^{2} = { \sqrt{31} }^{2}$

Option A is correct

${5}^{2} + {5}^{2} = { \sqrt{50} }^{2}$

But B isn't correct

Hope this helps ^-^
