Answer:

Step-by-step explanation:

B = 42°

Complement of B = 90°-B = 48°

:::::

3x-8 = 2x+1

x = 9°

:::::

A = 71°

Supplement of A = 180°-A = 109°

:::::

x + (5x) = 180°

x = 30°

:::::

A straight angle is 180°

:::::

78 = 5x-2

x= 16°

:::::

C = 110°

Supplement of C = 180°-C = 70°

:::::

119 + m = 180

m = 61°

then
1/x = (3/6) = (1/2)
so the answer would be
x = 2

Find the distance between the two points in simplest radical form.<br> (-5,8) and (-3, 1)
elixir [45]

Given:

The two points are (-5,8) and (-3,1).

To find:

The distance between the given two points in simplest radical form.

Solution:

Distance formula: The distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using distance formula, the distance between (-5,8) and (-3,1) is

d=\sqrt{(-3-(-5))^2+(1-8)^2}

d=\sqrt{(-3+5)^2+(-7)^2}

d=\sqrt{(2)^2+(-7)^2}

d=\sqrt{4+49}

d=\sqrt{53}

Therefore, the distance between two points (-5,8) and (-3,1) is \sqrt{53} units.
