Find the vertex form Y=3(x+3^2-34
Answer: I know that the answer is 47.
Step-by-step explanation: add up all the angles to get 180 degrees.
Answer:
ans: ii) 87° and iii) 60°
Step-by-step explanation:
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
