Anyone know the answer I’m lost…

Mathematics
1 answer:
Artist 52 [7]2 years ago
5 0

Answer:

#1: -1

#2: 1

Step-by-step explanation:

Anything raised to  the 0 power is 1, but in question 1 the negative is outside the parenthesis, so it makes it -1.

An angle is 21 degree more than twice its complement find it
jekas [21]

Answer: 67°

Step-by-step explanation:

Complementary angle refers to the angle that when added together will be equal to 90°.

Let the measurement of the angle's complement be x.

Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,

x + 2x + 21 = 90

3x + 21 = 90

3x = 90 - 21

3x = 69

x = 69°/3

x = 23°

Therefore, the angle will be:

= 2x + 21

= 2(23°) + 21°

= 46° + 21°

= 67°

The angle is 67°.

What's the fraction root of 9 over 49?
irakobra [83]
<span>√9/49

First you figure out the square root of 9 which is 3 since 3 x 3 equals 9. Then you find the square root of 49 which is 7 since 7 x 7 equals 49. Therefore, the answer is 3/7</span>

#2 Find the slope given the points (6,-12) and (15,-3)*
castortr0y [4]

Greetings :)

To find slope of two points we will need to use this equation:   \frac{y^2-y^1}{x^2-x^1}

 x^1     x^2     y^1    y^2  

( 6 , -12 ) ( 15 , -3 )

Now let's replace the equation with the numbers. (it will be a fraction).

\frac{-3-(-12)}{15-12}         =         \frac{9}{9}

The equation equals 9 over 9, which also equals 1.

The slope of the line is 1.

Find the value of x in the triangle shown below.<br> x =<br> 98°<br> 27°
Levart [38]

Answer: 55

Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.

Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.

Thus, we could label the points A, B, and C, and set up an algebraic expression.

Let A = 27, B = 98, and C = x.

A + B + C = 180°.

Substituting A, B, and C we get:

27 + 98 + x = 180°.

Adding, we get:

125 + x = 180°

Subtracting 125 by 180, we get:

x = 55°

Thus, the angle X is 55°.

We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
