Answer:

Step-by-step explanation:

do a squared plus b squared = c squared like

2 and 5 thingy squared by 2 + 6 squared = c squared

unsquare c and you get your answer

20.Solve the triangle: b = 100, c = 100, y = 70". If it is not possible, say so.This triangle is not solvable.Q = 40", a = 68.4,

saveliy_v [14]

Answer:

$\begin{gathered} \alpha=\text{ 40\degree} \\ \beta=\text{ 70\degree} \\ a=68.4 \end{gathered}$

Step-by-step explanation:

By the theorem of intern angles of a triangle, we know that the sum of all intern angles of a triangle must be 180°, therefore:

*There are two equal angles because there are two equal sides

$\begin{gathered} \alpha=180-70-70 \\ \alpha=\text{ 40\degree} \\ \beta=\text{ 70\degree} \end{gathered}$

Now, applying the law of sines, we can find side a. The law of sines is represented by the following equation:

$\frac{a}{\sin \alpha}=\frac{b}{\sin \beta}$

Hence, if b=100, alpha=40° and betha=70°, solve for a:

$\begin{gathered} \frac{a}{\sin (40)}=\frac{100}{\sin (70)} \\ a=\frac{100\cdot\sin (40)}{\sin (70)} \\ a=\text{ 68.4} \end{gathered}$

Find the equation of the line that is parallel to y=5x+1 and passes through the point (10, -1)

DaniilM [7]

Answer:

The required equation is 5x-y-51 = 0

Step-by-step explanation:

$the \: given \: equation \: is \\ y = 5x + 1 \\ 5x - y + 1 = 0 \\ the \: equation \: of \: the \: line \: \\ parallel \: to \: 5x - y + 1 = 0 \: \: is \\ 5x - y + k = 0 \\ since \: it \: passes \: through \: (10, - 1) \\ 5(10) - ( - 1) + k = 0 \\ 50 + 1 + k = 0 \\k = - 51 \\ the \: equation \: of \: the \: line \: parallel \: t o\: \\ 5x - y + 1 = 0 \: \: \: is \\ \: 5x - y - 51 = 0$
