<h2>Answer :</h2>

\large \bf \implies \angle{BAC} = 40 \degree

<h2>Step-by-step explanation :</h2>

\bf \implies  \angle{ABC} + \angle{BAC} = 90\degree [The acute angles of a right triangle are complementary]

\bf \implies  50x + 40x = 90\degree

<u>Substitute</u> :

\angle{BAC} = 40x \:  \: , \:  \: \angle{ABC} = 50x  \: into \: \angle{ABC} + \angle{BAC} = 90\degree

  • \sf{x =  1}

<u>Calculate 50x + 40x = 90°</u> ↑

  • \sf{\angle{BAC} = 40}

Substitute x = 1 into \bf{\angle{BAC} = 40x} ↑

\boxed{ \bold{\angle{BAC} = 40} }\:  \mathfrak{ans.}

What is the distance between the points (-4,0) and (-7, -14) ?​
vlada-n [284]

Answer:

Step-by-step explanation:

(-4,0) ; (-7, -14)

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(-7-[-4])^{2}+(-14-0)^{2}}\\\\ =\sqrt{(-7+4)^{2}+(-14)^{2}}\\\\=\sqrt{(-3)^{2}+(-14)^{2}}\\\\=\sqrt{9+196} \\\\=\sqrt{205} \\\\=14.3178

The length of the diogonals of a rectangular garden is 34m. If it's longer side measures 30m, find the perimeter of garden. ​
MakcuM [25]

Answer:

92 m

Step-by-step explanation:

Use the Pythagorean theorem to find the length of the shorter side.

Let w = length of the shorter side.

w^{2}  + 30^{2}  =  34^{2} \\ w^{2}  + 900 = 1156\\w^{2}  =  256\\w = \sqrt{256} = 16

The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m
