Right triangle means Pythagorean theorem!
a^2+b^2=c^2
if each leg (a and b) = x, then
x^2+x^2=c^2
2x^2=c^2
solving for c by taking the square root of both sides leaves

c=x×sqrt(2)

c must be positive since its a length, so no need for a +- I. this case

A triangle has one angle measuring 3X degrees a second angle measures 2X +20°
Lena [83]
Answer : x = 20

Explanation :
3x + 2x +20 + 4x - 20 = 180

(3+2+4=9)

9x + 20 - 20
The 20s cancel each other out because one is positive and the other is negative

9x = 180

9x/9 = 180/9

X = 180 divided by 9

X = 20

Identify the domain and range of this graph​
RSB [31]

Answer:

domain is [-3,3] & range is [-3,3]

Step-by-step explanation:

When given a graph of a circle and ask to solve range and domain....

First: <u>find the four points</u> of the circle:

(-3,0);(3,0);(0,-3);(0,3) .   <em> **Best to plot these points on this graph to understand where the points are and what we are looking at.</em>

Second: Look for <u>range(vertical directions/left and right) and domain(horizontal direction/up and down)</u>.

domain: x-values, first coordinate  (-3,0) & (3,0)

range: y-values, second coordinate (0,-3);(0,3)

Third: take what you know and solve domain and range*include bracket to show domain and range

domain is [-3,3] & range is [-3,3]
