I love these!

Okay, so this is a right angle. That means it is 90 degrees.

So far we know that on side of the angle is 47 degrees.

To get the other angle we will just subtract 90 - 47 = 43

Because the first angle is 90 degrees or right angle, then subtract
90 - 47 = 43

klasskru [66]

Answer:

50% of 3000

Step-by-step explanation:

49% is very close to 50% (half). 3,025 pounds is very close to 3,000 pounds.

Half of 3,000 pounds is 1,500 pounds.

Use the discriminant to determine the number of solutions and types of solutions for the quadratic equation, below. Then answer

Setler79 [48]

Answer:

A. Discriminant = 116

B. Number of solutions for the quadratic equation = 2

C. Type of solutions (circle one):Imaginary

D. Type of solutions (circle one):irrational

Step-by-step explanation:

The given quadratic equation is

${x}^{2} + 8x = 13$

We rewrite in standard form to get;

${x}^{2} + 8x - 13 = 0$

The discriminant is

$D = {b}^{2} - 4ac$

where a=1, b=8, c=-13

We substitute to get:

$D = {8}^{2} - 4 \times 1 \times - 13$

$D = 64 + 52$

$D = 116$

Since the discriminant is great than zero, we have two distinct real roots

If sin²(32°) + cos²(M) = 1, then what does M equal

Neko [114]

Answer:

M = 32°

Step-by-step explanation:

This is a trigonometric identity, that is

sin²x + cos²x = 1

where x in both cases is the same angle, thus

sin²32° + cos²32° = 1

Hence M = 32°
