2) 23 and 24 are complementary angles. If m 23 = (x + 24)º and m 24 = (x )º, then
adoni [48]

Answer:

m<23 = 57° & m<24= 33°

Step-by-step explanation:

You have to create an equation that equals 90°.

(x+24)+x=90

2x+24=90

2x=66

x=33

m<23 = 33+24= 57° so m<23= 57°

m<24= 33°

Choose a fraction that makes the following sentence true. 0.1 is a rational number because it can be written as ___.
pychu [463]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

0.1 is a rational number because it can be written as \dfrac{p}{q} form.

So, we can write it as

0.1=\dfrac{0.1}{1}\\\\=\dfrac{0.1\times 10}{1\times 10}\\\\=\dfrac{1}{10}

so, it can be written as \dfrac{1}{10}

Hence, option 'a' is correct.

PLEASE HELP ASAP!!!!! Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F, G). Which
aliya0001 [1]

Answer:

y -G = -1/3 ( x- F)

Step-by-step explanation:

The line on the plane has a slope

m = (y2-y1) /(x2-x1)

(0,-2) and (1,1)

   = (1- -2)/( 1-0)

   = (1+2)/(1-0)

    = 3/1

Perpendicular lines have slopes that multiply to -1

m * 3 = -1

Divide by 3

m = -1/3

The perpendicular line has a slope of -1

The point slope equation is

y - y1 = m(x-x1)

y -G = -1/3 ( x- F)
