Because the triangle  is isosceles the 2 base angles are equal  so adding up all the angles:-

2 (x - 2) + 4x + 10 = 180
2x - 4 + 4x + 10 = 180
6x = 180 + 4 - 10
6x = 174
x = 29 

3y  + (x - 2) = 180       Adjacent angles so
3y + 29 - 2 = 180
3y =  153

y =   51

BARSIC [14]

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively. Then the correct option is A.

<h3>What is an angle?</h3>

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

In the diagram, the measure of angle ∠8 is 124°, and the measure of angle ∠2 is 84°.

Angle ∠1 and ∠2 are supplement angles.

∠1 + ∠2 = 180°

∠1 + 84° = 180°

        ∠1 = 96°

Similarly, angles ∠7 and ∠8 are supplement angles.

∠7 + ∠8 = 180°

∠7 + 124° = 180°

          ∠7 = 56°

By the property of the opposite angles, we have

∠1 = ∠3 = 96°

∠2 = ∠4 = 84°

∠5 = ∠7 = 56°

∠6 = ∠8 = 124°

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively.

Then the correct option is A.

HELP ASAP!! Which representation shows y as a function of x ?
Marat540 [252]

Answer:

It is the first answer

Step-by-step explanation:

For it to be considered a function, each x-value can only corresponds (have) one y-value, however, y-values (even if they are the same y-value) can have multiple different x-values.
