Q1.

Angle BAD is adjacent to angle CAD

which means they are equal

so angle BAD = 26 degrees


Q2.

Angel BAC = the sum of angles BAD and CAD

because they are adjacent angles

To find the angles we solve the equations

9x-5 = 3x+7

9x-3x = 7+5

6x = 12

x = 12/6

x = 6

What two numbers multiply into (-24) and adds up to (-10)?
yKpoI14uk [10]

Two numbers multiply into (-24) and adds up to (-10) are 2 & -12

<u>Step-by-step explanation:</u>

Here we need to find two numbers , with the following info:

Let us assume that two numbers are x & y .

two numbers multiply into (-24):

Two numbers are x and y , and there multiply is -24 i.e.

⇒ x(y) = -24

two numbers adds up to (-10):

Two numbers are x and y , and there addition is -10 i.e.

⇒ x+y = -10 . .............. (1)

Let's solve this :

We know that , (x+y)^2 = x^2 +y^2 +2xy

⇒ (x+y)^2 = x^2 +y^2 +2xy

⇒ (-10)^2 = x^2 +y^2 +2(-24)

⇒ 100 = x^2 +y^2 -48

⇒ x^2 +y^2 =148

Now,

⇒ (x-y)^2 = x^2 +y^2 -2xy

⇒ (x-y)^2 = (148) -2(-24)

⇒ (x-y)^2 = (148) +48=196 = 14^2

⇒ x-y = 14     .......... (2)

Let's solve equation 1 & 2 by adding (1)+(2):

⇒ (x+y)+(x-y) = -10 +14

⇒ 2x=4

⇒ x=2

Putting value of x=2 in x-y = 14 :

⇒ 2-y = 14

⇒ y = -12

Therefore, two numbers multiply into (-24) and adds up to (-10) are 2 & -12.
