Find x and y by using the image

x = 90degrees and y = 45degrees

Step-by-step explanation:

To get x, we will use the theorem that states that 'the measure of the vertex angle is equal to the half of the difference of the measures of its intercepted arcs. Hence;

45 = 1/2 (180 - x)

Cross multiply

45*2 = 180 - x

90 = 180 - x

x = 180 - 90

x = 90degrees

Let the angle o the same line with y be z. Hence;

z = 1/2(180+x)

z = 1/2(180+90)

z = 1/2 * 270

z = 135

Sum of angle on a straight line is 180 degrees

z + y = 180

135 + y = 180

y = 180 - 135

y = 45

Hence x = 90degrees and y = 45degrees

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
