Two exterior angles of a triangle measure 103(degrees)and 126(degrees)what is the measure of the third exterior angle

The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.

Example: How many degrees are in the third angle of a triange whose other two angles are 40o and 65o? 180o - 40o -65o = 75o

Step-by-step explanation:The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.

Example: How many degrees are in the third angle of a triange whose other two angles are 40o and 65o? 180o - 40o -65o = 75o

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
