The sum of three numbers is 117 . the third number is 3 times the second. the first number is 8 less than the second. what are t

tamaranim1 [39]

Let the second number be x.

First number = x - 8

Third number = 3x

Sum of the numbers = 117

x - 8 + x + 3x = 117

5x = 125

x = 25

Thus,

The first number is 17. The second number is 25. The third number is 75.

Solve the system. Enter the smallest x-coordinate first

pentagon [3]

$y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

Step-by-step explanation:

Solving the following system of equations:

$x^2-y=1\\2x^2+y^2=17$

Let

$x^2-y=1\,\,\,(1)\\2x^2+y^2=17\,\,\,(2)$

Putting value of x^2 in eq(2)

$x^2 = 1+y\\Putting\,\,value\,\,of\,\,x^2\,\,in\,\,eq(2)\\2(1+y)+y^2=17\\2+2y+y^2=17\\y^2+2y+2-17=0\\y^2+2y-15=0\\Factorizing:\\y^2-3y+5y-15=0\\y(y-3)+5(y-3)=0\\(y+5)(y-3)=0\\y+5=0 \,\,and \,\, y-3=0\\y = -5 \,\,and \,\, y=3$

Now, finding value of x

Putting y=-5

$x^2 = 1+y\\x^2=1-5\\x^2=-4\\Taking\,\,square\,\,root\\x= \pm2i$

y=-5, x= 2i and y=-5 , x= -2i

Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer

Putting y=3

$x^2 = 1+y\\x^2=1+3\\x^2=4\\Taking\,\,square\,\,root\\x= \pm2$

So, $y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

Find m angle C<br> 62 degrees<br> 70 degrees

wlad13 [49]

Answer:

48°

Step-by-step explanation:

..,.............,...........

CDB = ABD( given)

CBD= ADB( given)

Now,

CBD+CDB+C = 180°

70°+62°+ C = 180°

C= 180°-132°

C= 48°
