Well 0.65 as a percentage is 65% which is 65/100. So in the simplest for it would be the highest number going into both which would be 5 and then divide both numbers by 5.
65/5=13
100/5=20
So the answer for this question would be 13/20

If f(x)= 3 over x+2- square root x-3 f(19)=

PSYCHO15rus [73]

F(19)= (3/(19+2)) - sqrt(19-3)
= (3/21) - sqrt(16)
= (1/7) - 4
= (1/7) - (28/7)
= -27/7
= - 3 6/7

What is the value of tan A?

Ronch [10]

For the given triangle, the tan of angle A equals $\frac{3}{4} = 0.75.$

Step-by-step explanation:

Step 1:

In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

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

Step 2:

The opposite side's length = 6 cm.

The adjacent side's length = 8 cm.

$tan A = \frac{oppositeside}{adjacent side} = \frac{6}{8} = \frac{3}{4} = 0.75.$

Help pls <br> Show workings

vitfil [10]

- the type of pair is vertical angle.

- to find x:

-- vertical angles are equal.

4x + 10 = 5x - 1

10 = x - 1

x = 11
