À level 8) Write and solve an equation to find the value of x. What is the mea-
sure of each labeled angle?

X=30

<CBD=30°

<BCD=60°

<CDB=90°

<ABC=150°

Объяснение:

Сумма углов в треугольнике равна 180° (The sum of all angles in the triangle is equal 180°)

<CBD+<CDB+<BCD=180°

x+2x+3x=180

6x=180

x=180/6

x=30

<CBD=30°

<BCD=30*2=60°

<CDB=30*3=90°

<ABC=30*5=150°
