Find the lettered angles in each of the following (see image ). Sorry for the wobbly drawing.
please show workings.​

x = 252°, y = 126° , z = 54°

Step-by-step explanation:

( Hopefully I've read the size of the angle 126° correctly )

The central angle x is twice the inscribed angle, that is

x = 2 × 126° = 252°

∠ y = 126° ( angles on the circumference subtended by the same arc )

y and z are adjacent angles and are supplementary , that is

y + z = 180°

126° + z = 180° ( subtract 126° from both sides )

z = 54°

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
