Hope this helps!
May I please have brainliest? :D
Answer:
Step-by-step explanation:
m4 + m3 = 180 (Supplementary angle on 1 line)
m6 +m3 = 180 (Supplementary angle)
-> m6=m4
-> x+80 = 4x-10
-> 90 = 3x
-> x = 30
-> m6=m4 = 80+30 = 110
...
m1+m4 = 180 (Supplementary angle on 1 line)
-> m1 = 180 -110 = 70
Answer:
y=9x-17; x=17/9 or x=1 8/9 or x=1.8
y=x+23; x= -23
Step-by-step explanation:
y=9x-17
0=9x-17 (Move variables to the left-hand side and change its sign)
-9x=-17 (Divide both sides of the equation by -9)
x=17/9, x=1 8/9, or x=1.8
y=x+23
0=x+23 (To find x-intercept/zero, substitute y=0)
-x=23 (Move variable to the left-hand side and change its sign)
x= -23 (Change the signs on both sides of the equation)
x= -23
Answer:
We can use the Pythagorean Theorem to help determine if a triangle is a right triangle, if it is acute, or if it is obtuse. ... Conversely, if \begin{align*}a^2 + b^2 < c^2\end{align*}, then lengths \begin{align*}a, \ b\end{align*}, and \begin{align*}c\end{align*} make up the sides of an obtuse triangle.
