Hello there! And welcome to brainly . com, your #1 asking and answering site!

Answer: 20

<em>Why?</em>

So we need to substitute x for 3, so do that. (7x-1 => 7 * 3 - 1) Multiply 7 by 3. (7 * 3 == 21) Finally, subtract by one. (21 - 1 == 20) Therefore, your answer is 20.

Hope this helped you, and have a beautiful day!! ♥

7x - 1 = 20

7 times 3 is 21, 21 minus 1 is 20

Answer:

∠4 and ∠3

∠4 and ∠5

∠3 and ∠6

Step-by-step explanation:

A pair of angles is said to be supplementary when the 2 angles add up to give 180°.

Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.

Thus, since m< 3 is given as 90°, m<4 = 90°.

m<4 + m<3 = 180°.

Therefore, <4 and <3 are supplementary.

<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
