jeka57 [31]

Answer:

32°, 58°

Step-by-step explanation:

Let one acute angle measure x.

The other acute angle measures 2x - 6.

The sum of the measures of the acute angles of a right triangle is 90.

x + 2x - 6 = 90

3x - 6 = 90

3x = 96

x = 32

2x - 6 = 2(32) - 6 = 58

Answer: 32°, 58°

PLEASE HELP! WILL MARK BRAINLIEST!
Kaylis [27]

Answer:

320 meters

Step-by-step explanation:

x² + 200x = 166400

It's a square, area should be side²

x² + 2(x)(100) = 166400

x² + 2(x)(100) + 100² = 166400 + 100²

(x + 100)² = 176400

x + 100 = 420

Since these are sides, we just consider the positive square root

x + 100 = 420

x = 320m

We're given a parabola

y=x^2-4

and a line

y = 2x+b

The zeros of the parabola are

0=x^2-4

4=x^2

x=\pm 2

We see that (-2,0) is on the line as well:

y = 2x+b

0 = 2(-2)+b

b=4

Choice D
