Question

find
(I) angle x
(ii) angle y and angle z​

Answer 1

Answer:

I)68°

ii) 112°

Step-by-step explanation:

angle ACB + angle ACD = 180° (straight angle)

x + 112° = 180°

x = 180 - 112

x = 68°

angle y + angle z = 112°. (exterior angle theorem)

Note:

Exterior angle theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle.
