Answer:

y = 25 degrees

Step-by-step explanation:

straight line has 180 degrees

so 180 - 115 = x which is 65 degrees

traingle has 180 also

65 + 90 = 155          180 - 155 = y which is 25 degrees

The triangle on the other side is the equivalent.

Answer:

y = 25°

Step-by-step explanation:

x = 180° - 115° (115° and x are supplementary angles)

x = 65°

In the triangle,

x + y + 90° = 180°

65° + 90° + y = 180°

155° + y = 180°

Subtract 155 from both sides,

y = 180° - 155° = 25°

Answer:P\left ( A\right )=0.45

P\left ( B\right )=0.32

Step-by-step explanation:

Given

P\left ( A\cup B\right )=0.626

P\left ( A\cap B\right )=0.144

and we know

P\left ( A\cup B\right )=P\left ( A\right )+P\left ( B\right )-P\left ( A\cap B\right )

0.626=P\left ( A\right )+P\left ( B\right )-0.144

0.77=P\left ( A\right )+P\left ( B\right )-------1

as it is given

A and B are independent therefore

P\left ( A\cap B\right )=P\left ( A\right )\cdot P\left ( B\right )

0.144=P\left ( A\right )\cdot P\left ( B\right )

Substitute value of P\left ( B\right ) in 1

0.77=P\left ( A\right )+\frac{0.144}{P\left ( A\right )}

on solving P\left ( A\right )=0.45

P\left ( B\right )=0.32
