Answer:

m∠2 = 103°

Step-by-step explanation:

Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180.

Answer:

Step-by-step explanation:

The sum of two supplementary angles sum up to 180°

Hence <1+<2 = 180°

Given

<1 = 77

Substitute and get <2

<1+<2 = 180

77+<2 = 180

<2 =180-77

<2 = 103°

Hence the measure of <2 is 103°

A área do círculo mede 196 π cm². Qual a medida do seu raio?

AleksandrR [38]

Hey there!!

The area of a circle = πr²

The area is given as 196π

Hence,

196π = πr²

... r²= 196

... r = √196

... r = 14

<em>Hence, the radius is 14 cm. </em>

Based on the table of values below, find the slope between points where x = 1 and where x = 4.

Andre45 [30]

$\bf \begin{array}{llll}
x&\boxed{1}&3&\boxed{4}\\\\
y&\boxed{8}&6&\boxed{-1}
\end{array}\\\\
-------------------------------\\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ 8}})\quad 
% (c,d)
&({{ 4}}\quad ,&{{ -1}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-1-8}{4-1}\implies \cfrac{-9}{3}\implies -3$
