1) 14°

2)117°

3) 78°

4) 66°

5) 64°

6) 28°

7)35°

8) 48°

Step-by-step explanation:

just subtract both angles from 180 because all triangle's angles always add up to 180°

1. ) 14

2.) 117

3.) 78

4.) 66

5.) 64

6.) 34

7.) 45

8.) 48

the person before me i dont think dod did their math right bc some of their math answers are wrong on 5 through 8 i think it is.

NOW HERE'S HOW TO DO IT WITH EXAMPLES OF YOUR QUESTIONS

in triangles all angles added up cant be more than 180 degrees . basically you take 180 and subtract the known angles and what is left over is the unknown angle

example question 1.) 180-112-54=14

question 2.) 180-38-25=117. i hope this helps. man i should have typed faster id be first. owell goodluck

Man borrows 26,000 for 3 years with simple interest 1.7 percent determine the amount of money repay after three years

Naya [18.7K]

Answer:

$1,326

Step-by-step explanation:

You are going to want to use the simple interest formula for this.

$I=Prt$

I = interest amount

P = principal amount

r = interest rate

t = time

First, change 1.7% into its decimal form:

1.7% -> $\frac{1.7}{100}$ -> 0.017

Next plug in the values into the equation:

$I=26,000(0.017)(3)$

$I=1,326$

After three years, he must repay $1,326.

Given the expression: 3x10 − 48x2

BartSMP [9]

Factorization involves representing an expression with smaller terms.

When the greatest common factor is factored out, the equivalent expression is: $3x^2(x^8 - 16)$ .
The complete factored expression is: $3x^2(x^4 - 4)(x^4 + 4)$

The expression is given as:

$3x^{10} -48x^2$

The GCF of $3x^{10}$ and $48x^2$ is $3x^2$ .

So, we have:

$3x^{10} -48x^2 = 3x^2 \times x^8 - 3x^2 \times 16$

Factor out $3x^2$

$3x^{10} -48x^2 = 3x^2(x^8 - 16)$

To factorize the expression completely, we express $x^8$ and $16$ as squares.

So, we have:

$3x^{10} -48x^2 = 3x^2((x^4)^2 - 4^2)$

Apply difference of two squares

$3x^{10} -48x^2 = 3x^2(x^4 - 4)(x^4 + 4)$

So, the complete factor of $3x^{10} -48x^2$ is $3x^2(x^4 - 4)(x^4 + 4)$

Write an equation of the line that passes through a pair of points: (-5, - 2), (4, 5)

attashe74 [19]

Answer (assuming it can be written in slope-intercept form):

$y = \frac{7}{9} x+\frac{17}{9}$

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of the given points into the formula and solve:

$m = \frac{(5)-(-2)}{(4)-(-5)} \\m = \frac{5+2}{4+5} \\m = \frac{7}{9}$

So, the slope is $\frac{7}{9}$ .

2) Now, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line. Substitute $m$ , $x_1$ , and $y_1$ for real values.

Since $m$ represents the slope, substitute $\frac{7}{9}$ for it. Since $x_1$ and $y_1$ represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form ( $y = mx + b$ format) and find the following answer:

$y-(5) = \frac{7}{9} (x-(4))\\y-5 = \frac{7}{9} (x-4)\\y -5=\frac{7}{9} x-\frac{28}{9}\\y = \frac{7}{9} x-\frac{28}{9} +\frac{45}{9}\\y = \frac{7}{9} x+\frac{17}{9}$
