Question

(a) NOT TO SCALE 108%a b From the diagram above, calculate the size of angle Answer (ii) b, Answer (iii) c. Answer [1] [1] [1]​

Answer 1

Answer:

The first way starts by constructing part of an equilateral triangle, then bisecting the 60 degree angle. The second method starts by constructing a rhombus with 60 and 120 degree angles, then joining the opposite vertices to leave the 30 degree angle.

x = 67

y= 45

z = 20

Answer 2

Answer:

i don't know perfectly but this can be the answer

Step-by-step explanation:

the sum of interior angles of a quadrilateral= 360°

360° - 180° = 180°

therefore,

$\frac{180}{3}$

= 60°

Therefore, a= 60*

b= 60°

c= 60°
