they forget the last step which is to take the square root of the sum

7) a = 4

b = 17

a² + b² = c²

4² + 17² = c

16 + 289 = c²

305 = c²

√305 = c

17.464249196572980 = C

Hey need some help with this problem, its trigonometry with right triangles using SohCahToa if you can give me a hand it would b

For the given triangle, the value of x equals 30.9892 units.

Step-by-step explanation:

Step 1:

In the triangle, the angle is 40°, the opposite side has a length of 26 units, the adjacent side has a length of x units while the hypotenuse is not given.

To determine the value of x, we determine the value of the tan of the given triangle.

To calculate the tan of angle A we divide the opposite side's length by the the adjacent side's length.

$tan A = \frac{oppositeside}{adjacent side}.$

Step 2:

The length of the opposite side = 26 units.

The length of the adjacent side = x units.

$tan A = \frac{oppositeside}{adjacent side}, tan 40 = 0.8390, tan A = \frac{26}{x} .$

$0.8390 = \frac{26}{x} , x = \frac{26}{0.8390} = 30.9892.$

So x measures 30.9892 units.

Y1=4(5x-1), y2-=5x+1 and y1 is 344 more than 2 times y2

alisha [4.7K]

$y_1=4(5^x-1)$ and $y_2=5^x+1$

$y_1=344+2y_2$
$y_1=344+2(5^x+1)$
$4(5^x-1) = 344 + 2(5^x+1)$
$(4)(5^x)-4=344+2(5^x)+2$
$4(5^x)-2(5^x)=344+2+4$
$2(5^x)=350$
$5^x= \frac{350}{2}$
$5^x=175$
$log(5^x)=log(175)$
$x(log(5))=log(175)$
$x= \frac{log175}{log5}$
$x=3.21$ (rounded to two decimal places)
