Answer:
B
Step-by-step explanation:
-the base angles are 34, so the total value of both base angles is 68
-an isosceles triangle is equal to 180
-subtract 68 from 180 for the answer, so the equation is 68+x=180

Answer:
tanθ = -1
m=tanθ = -1
Step-by-step explanation:
Step 1:-
using formula m=tanθ
Given straight line is x+y=0
The given straight line is passing through the origin so y = -x
straight line is passing through the origin so y = m x
m = -1
Step3:-
The line with equation x+y=0 with the terminal side of an angle θ in standard position in Quadrant II i.e., θ = 90+45=135
m = tanθ
m = tan(90+45)
m = - cot 45
m = -1
Step4:- m =tanθ =-1
