What is the measure of angle A?

Answer:

The measure of A is 30

Step-by-step explanation:

In order to find the value of A, we first need to find x. We can do this by measuring all the interior angles and setting equal to 180. Since 8x + 4 is vertical with the interior angle, we know that it is the same. Also since 130 creates a supplement with the interior angle, we know that the interior angle is equal to 50.

3x - 6 + 8x + 4 + 50 = 180

11x + 48 = 180

11x = 132

x = 12

Now that we have x, we can find A.

A = 3x - 6

A = 3(12) - 6

A = 36 - 6

A = 30

Solve for the values of x and y in the diagram
qaws [65]

Answer: y = 0.5, x = 50

Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:

a triangle has 180 degrees so we subtract the given 50 which gives us 130

2(2y + 64) = 130

4y + 128 = 130

y = .5

This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:

2(45 - x/4) = 65

x = 50

This means the bottom 2 angles of the second triangle are both 32.5.

Supplementary means they add up to 180
Adjacent means they are next to each other
Complementary means they add up to 90
