Answer:

D

(Please vote me Brainliest if this helped!)

Step-by-step explanation:

The angle shown is a right angle. Right angles have a total of 90°.

Therefore, I simply multiplied each answer by 4 because 4(x) = (answer).

A. 4 (14) = 56 + 42 = 98° ≠ 90° INCORRECT

C. 4 (10) = 40 + 42 = 82° ≠ 90° INCORRECT

B. 4 (16) = 64 + 42 = 106° ≠ 90° INCORRECT

D. 4 (12) = 48 + 42 = 90° = 90° CORRECT

An easier way to solve this problem is by simply just subtracting and dividing:

90 - 42 = 48

48 ÷ 4 = 12

What's the solution set of –5 < 2x – 1 < 3?
Dmitry [639]

Answer:

The answer is - 2 < x < 2

Step-by-step explanation:

–5 < 2x – 1 < 3

Add 1 to both sides to eliminate - 1

That's

- 5 + 1 < 2x - 1 + 1 < 3+ 1

- 4 < 2x < 4

Divide both sides by 2

That's

- 4/2 < 2x/2 < 4/2

The final answer is

<h3 /><h3>- 2 < x < 2</h3>

Hope this helps you
