Hello There!
The exterior angle of a triangle rule is that the exterior angle is equal to the sum of the interior opposite angles
So essentially what I'm saying is that
z = 29 + 39
29+39=68 therefore the measure of angle z is 68
Multiply 10 cm by 0.4 and mult. 30 cm by 0.4 also:
The height of the smaller triangle is then 4 cm and the length of the base is 12 cm.
