Madison drew angle DEF In her triangle, angle d is represented as x degrees. The measure of Angle E is half the measure of angle

Olenka [21]

D = x
E = .5x
F = 2x-2

(x)+(.5x)+(2x-2)=180
3.5x-2=180
3.5x=182
x=52

F = 2(52)-2 = 102 degrees

Answer:

1. Line BD = 180 degrees

2. Angle C = 58 degrees

3. 180 - 58 = 122 degrees (angle x)

4. Angle B = 60 degrees

5. Sum of interior angles = 180 degrees

6. 180 - angle B - angle C = angle A

7. 180 - 60 - 58 = angle A

8. 62 = angle A (angle y)

Angle x is 122 degrees

Angle y is 62 degrees

Alinara [238K]

Answer:

1. {5,-9}

2.{4}

3.{9/2}

Step-by-step explanation:

The equation $f(x)=x+\lvert 2x-3 \rvert=12$ can be solved as follows:

$x+\lvert 2x-3 \rvert =12\,\,\,\text{(given equation)}$

$\lvert 2x-3 \rvert =12-x$

$2x-3=12-x\,\,\text{or}\,\,2x-3=-(12-x)$

$3x=15\,\,\text{or}\,\,\x=-9$

Then, the solutions of the equation are $x=5, x=-9$ .

Now, if $g(x)=5x-3+\lvert x+4\rvert$ , we can solve the equation $g(a)=4a+9$ as follows:

$5a-3+\lvert a+4 \rvert =4a+9$

$\lvert a+4\rvert =4a+9-5a+3$

$a+4 =-a+12\,\,\text{or}\,\,a+4=-(-a+12)$

$2a=8\,\,\text{or}\,\,4=12$

So, the unique solution of this last equation is $a=4$

The last equation is $h(x-1)=x-3$ , where $h(x)=\lvert x \rvert -2x+5.$ . To solve this equation we can proceed as follows:

$h(x-1)=x-3$

$\lvert x-1\rvert -2(x-1)+5=x-3$

$\lvert x-1 \rvert -2x+2+5=x-3$

$\lvert x-1\rvert =3x-10$

$x-1=3x-10\,\,\text{or}\,\,x-1=-(3x-10)$

$-2x=-9\,\,\text{or}\,\,4x=11$

$x=9/2\,\,\text{or}\,\,x=11/4$

But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
