Answer: x=80°
Explanation:
To find the exterior angle x we first need to find the last corner angle (a) of the triangle. The angles of triangles add up to 180° so we can use the formula: 25+55+a=180
Solving formula:
25+55+a=180
80+a=180
(Subtract 80 from both sides)
a=100°
Now that we know a=100 we can find the exterior angle. a+x=180 because the angles are on a straight line which equals 180°
a+x=180
100+x=180
(Subtract 100 from both sides)
x=80°

Answer:
x= 7/5 (1 2/5 or 1.4)
Step-by-step explanation:
Move the variable to the left-hand side and change its sign.
12x-15+3x=6
Move the constant to the right-hand side and change its sign.
12x+3x=6+15
Collect like terms.
15x=21
Divide both sides of the equation by 15.
x=7/5 (1 2/5 or 1.4)
The point-slope form:
We have the points (-5, 15) and (20, 25). substitute:
