Complementary angles add up to 90 degrees.

Which means.. the equation is
8x-23+7x-7=90
Combine like terms you should get
15x-30=90
Add 30 on both sides
15x=120
Divide 15 x=8
Plug in 8 to (8x-23)
8(8)=64-23=41

Please help on this... Fine the perimeter and the area of this.

leva [86]

Answer:

p = 18 in

a = 25 in²

Step-by-step explanation:

perimeter = sum of the sides

p = 4 1/3 + 5 1/3 + 8 1/3

p = 18 in

Area = 1/2 * base * height

a = 1/2 * 8 1/3 * 6

a = 1/2 * 50

a = 25 in²

Y = x² - 4x convert from standard to vertex form

Pepsi [2]

Answer:

$y = (x-2)^{2} -4$

Step-by-step explanation:

To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so $2^{2}$

$y + ? = x^{2} - 4x + ?$

$y + 2^{2} = x^{2} - 4x + 2^{2}$

$y + 4 = x^{2} - 4x + 4$

Now we can factor the expression

$y + 4 = (x-2)^{2}$

Move the 4 to the other side to isolate y which changes the sign

$y = (x-2)^{2} - 4$
