HELP// On a piece of paper, use a protractor to construct a triangle with angle measures of 20° and 30°.

1 answer:

3 0

Add the two angles together then subtract 180 to find the third angle which equals 130 degrees so you have all your angles now you need the definitions for acute, obtuse, and right angle

right angle has a 90 degree angle so that cant be it

an acute angle is less than 90 degrees so that is not it

obtuse angle is larger than 90 degrees so that must be the correct answer.. the correct answer is obtuse

What is 1/x∧-3/6 and how do you get to that answer?

Answer:

$x^\frac{1}{2}$

$\sqrt{x}$

Step-by-step explanation:

$\frac{1}{x^\frac{-3}{6}}$

I'm going to reduce -3/6 to -1/2 by dividing top and bottom of -3/6 by 3.

$\frac{1}{x^\frac{-1}{2}}$

Now I'm going to get rid of the negative exponent by moving x to the top; so -1/2 will change to 1/2 instead when doing this:

$1x^\frac{1}{2}$

$x^\frac{1}{2}$

$\sqrt{x}$

Please let know if I read the problem right:

$\frac{1}{x^\frac{-3}{6}}$

Ad libitum [116K]

Answer:

a) 9+(-3) + (-2) = 9 -5 = 4> 0 ⇒ Positive Sum

b) -12 +1 +11 = -12 +12 5 = 0 ⇒ Zero Sum

c) -3 +8 + (-4) = -7 + 8 -5 =-1 < 0 ⇒ Negative Sum

d) -4+9+(-10) = 9 -14 = -5 < 0 ⇒ Negative Sum

e) 3+(-2) + (-4) = 3 -6= -3 < 0 ⇒ Negative Sum

f) 2 + (-4) + 2 = 4 -4 = 0 ⇒ Zero Sum

Step-by-step explanation:

Positive Sum is defined as the condition in which the Sum of total of gains and losses is GREATER THAN ZERO.

Zero Sum is defined as the condition in which the Sum of total of gains and losses is EQUAL TO ZERO.

Negative Sum is defined as the condition in which the Sum of total of gains and losses is LESS THAN ZERO.

Now, here

a) 9+(-3) + (-2) = 9 -5 = 4> 0 ⇒ Positive Sum

b) -12 +1 +11 = -12 +12 5 = 0 ⇒ Zero Sum

c) -3 +8 + (-4) = -7 + 8 -5 =-1 < 0 ⇒ Negative Sum

d) -4+9+(-10) = 9 -14 = -5 < 0 ⇒ Negative Sum

e) 3+(-2) + (-4) = 3 -6= -3 < 0 ⇒ Negative Sum

f) 2 + (-4) + 2 = 4 -4 = 0 ⇒ Zero Sum

Label the sides of the right triangle.*2 pointsCaptionless ImageA) Hypotenuse = 8 m, Adjacent = 15 m, Opposite = 17 mB) Hypotenu

Bingel [31]

Given:

There are given that the right angle triangle, UVW.

Where,

$\begin{gathered} UV=8m \\ VW=15m \\ UW=17m \end{gathered}$

Explanation:

According to the concept:

The hypotenuse is defined as the longest side in the right-angle triangle.

The perpendicular side is defined by the perpendicular base angle.

And,

The adjacent side is defined by the leg of the right-angle triangle.

Final answer:

Hence, the correct option is D.
