Two lines intersect. Find the value of b and c.
bº
42°

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
