Base=(180°-vertex)/2=(180-82)/2=98/2=49°
base angles are 49°
Answer:
sin(x)=
/ 12, cos(x)=5/12, tan=
/ 5
Step-by-step explanation:
segment YZ is length a, we need to find a
segment XZ is length 5
segment XY is length 12
XYZ is a right triangle, so a^2 + b^2 = z^2, so
a^2 + 5^2 = 12^2, simplify
a^2 + 25 = 144, subtract 25
a^2 = 119
a = ![\sqrt{119\\}](https://tex.z-dn.net/?f=%5Csqrt%7B119%5C%5C%7D)
then we can determine all the trig ratios

/ 5
Answer: x=+2
Step-by-step explanation:2x-6=12x-26
We move all terms to the left:
2x-6-(12x-26)=0
We get rid of parentheses
2x-12x+26-6=0
We add all the numbers together, and all the variables
-10x+20=0
We move all terms containing x to the left, all other terms to the right
-10x=-20
x=-20/-10
x=+2
Answer: 0 -> -8, 2 -> -2, 4 -> 4
Step-by-step explanation: Just follow the equation
-(-z + 3) equals z - 3
5 = z - 3
z = 8
