<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.}

Find the solution of the system of equations.
avanturin [10]

Answer:

3

Step-by-step explanation:

The number is 3.

Step-by-step explanation:

Finding the Number

To find the number, we have to translate the problem above to an algebraic equation. The algebraic equation refers to the statement of the equality of two algebraic expressions.

Equation:

Let "x" be the number.

4 is divided by a number - 4/x

3 divided by the number decreased by 2 - 3/x-2

"4 is divided by a number is equal to 3 divided by the number decreased by 2"

4/x = 3/x-2

Solution:

Cross multiply.

4/x = 3/x-2

x(3) = 4(x-2)

3x = 4x - 8

(Combine similar terms.)

3x - 4x = - 8

- x = - 8

- x/- 1 = - 8/- 1

x = 8

Final Answer:

8

Checking:

4/x = 3/x-2

4/8 = 3/8-2

1/2 = 3/6

1/2 = 1/2 ✔

Which statement about the system of equations is true?
vagabundo [1.1K]
8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)

(2) x 2:
10 x - 6y = 4.4 --------(2a)

(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73

There is 1 set of solution to it. (Answer C)
