Answer:

You would do this problem like a normal varible problem. x=10

Step-by-step explanation:

Since 9x is a right angle the inside would also be 9x

9x+4x+10+40=180

180 because that is how much a triangle equals

combine like terms

13x+50=180

subtract 50 from both sides

13x=130

divide by 13

x=10

<u>Hope this helps!</u>

1. sin(x+20) = cos(2x+10)<br> 2. sin (2x+14) = cos(x-5)

lakkis [162]

Answer:

x=20°

x=27°

Step-by-step explanation:

sin(x+20)=cos (2x+10)

=sin (90-(2x+10))

so x+20=90-(2x+10)

x+20+2x+10=90

3x=90-30

3x=60

x=60/3=20

2x+14+x-5=90

3x+9=90

3x=90-9=81

x=81/3=27

Determine whether the origin is included in the shaded region and whether the shaded region is above or below the line for the g

kati45 [8]

Answer:

Option: D is correct.

Step-by-step explanation:

since we are given a inequality as:

$y$

Clearly from the graph of the following inequality we could see that the origin is included in the shaded region and the shaded area is below the line.

Also it could be seen that if we put the origin points i.e. (0,0) in the inequality than 0<2 and the condition is true and hence origin is included in the shaded area.

Hence, option D is true.

A lender will make an 80% loan-to-value loan on a property that is appraised for $72,250 and sells for $73,500. If the buyer has

user100 [1]

Answer:

$1250

Step-by-step explanation:

The loan can be made for up to ...

0.80 × $72,250 = $57,800

For a selling price of $73,500, the amount not funded by the loan will be ...

$73,500 -57,800 = $15,700

This is more than the buyer has saved by ...

$15,700 -14,450 = $1,250

The buyer will need $1250 in additional funds.
