<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.}

II. Perform ratio 70/100 = 42,000/x

                       70*x = 100 * 42,000

                        70x = 4,200,000

                            x = 60,000

III. If you perform 30/100 = x/60,000 will be 42,000

Sorry for late.

Find the missing lengths.
Rama09 [41]

Answer:

x = 5√2

Step-by-step explanation:

The triangle on the right is a special right triangle, so we know that the adjacent side to 60° is 5. Since the left triangle is a 45-45-90, the hypotenuse is the leg times √2, so the value of x is 5√2
