Find the value of. x part 1c​

The bisector splits this shape into two triangles. It is easier if we find the degrees of each triangle in this shape separately

We know that one angle of the top triangle is 65 degrees. Since another angle is congruent to the known angle we can assume that the other angle is 65 degrees as well. You can see this labeled in the image below.

The sum of all the angles of a triangle is 180 degrees. Since we know the degrees of two angles, which are both 65 degrees, we can make a formula to find the third angle:

180 = 65 + 65 + x

180 = 130 + x

50

This means that the last angle is 50 degrees

^^^We need to know this so that we can find the angle complimentary to the 50 degree angle, which will be the angle that is included in the bottom triangle

Complimentary angles are angles who's sum is 90 degrees. You can find the 50 degree angles complimentary angle by making a formula like so:

90 = 50 + x

40

Now we have the first angle of the second triangle. The second two angles can be found easily. Since the other two angles are congruent all we need to do is subtract 40 from 180  then divide the answer by 2 like so:

180 - 40 = 140

140 / 2 = 70

The other two angles are 70 degrees!

The measure of angle 2 is supplementary to one of the 70 degree angles. This means that you can find the value of angle 2 by subtracting 70 from 180

180 - 70 = 110

To find x set the equation equal to 110 and solve

110 = x + 120

x = -10

Hope this helped!

Quick plz help asap marking brainliest for first answer as long as you include steps !!!
Akimi4 [234]

Answer:

a=2.48

c=9.52

Step-by-step explanation:

a+c=12

4a+7.5c=72.5 Given


a+c=12

-4a-7.5c=-72.5 multiply the equation by negative 1


-3a-6.5c=-60.5 simplify


-3a=-60.5+6.5c add 6.5c to both sides


a=-20.17+2.17c divide it by 3

now you would take that equation and plug it into an equation you already have since you have something to plug in for a, the easiest one to do is a+c=12

(-20.17+2.17c)+c=12 plug in the equation


-20.17+3.17c=12 simplify by solving for c


3.17c=30.17 add 20.17 to both sides


c=9.52 divide both sides by 3.17

now since you have found c, you can plug it in to you equation to solve for a now (use the ones from the second step).  I am using the equation a+c=12.

a+9.52=12 plug in the variable and solve for a


a=2.48 subtract 9.52 to both sides


a=2.48

c=9.52

Value (in billions) 2017 2018
Tomtit [17]

The Owner's Equity for commercial banks in  2017-2018 is $0.4 billion.

The given is,

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

<h3 /><h3>What is the formula for the total liabilities?</h3>

Total liabilities = deposits + borrowings

So we have Borrowings = total liabilities - deposits

Borrowings in 2017

= $14.60 - 11.90

= $2.70 billion

Borrowings in 2018

= $14.80 - $12.20

= $2.60 billion

Borrowings from 2017-2018

= 2.60 - 2.70

= $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017

= $16.2 - $14.6

= $1.6 billion

Owner’s equity in 2018

= $16.8 - $14.8

= $2 billion

Owner's Equity from 2017-2018

= 2 - 1.6

= $0.4 billion
