Answer:

x = 1.

Step-by-step explanation:

5(x+4) =25

= 5x+20 = 25

5x = 25-20

5x= 5

therefore x = 1.

i need to find the measure of angle b in a right triangle... the base is 4. they hypotenuse is 9 and angle c is the right angle.
Romashka [77]
One way to solve this question is through trigonometry. :)

If you've learnt trigonometry, here are the basic formulas:
SOH CAH TOA (These formulas only apply for right-angled triangles)

Sin(angle) = (Side that is Opposite of angle)/(Hypotenuse)

Cos(angle) = (Side that is Adjacent of angle)/(Hypotenuse)

Tan(angle) = (Side that is Opposite of angle)/(Side that is Adjacent of angle)

In this case, we should use sine of b (the angle at the top of triangle as indicated in your question), where the opposite side is the base (I.e. 4 indicated in your question) and the hypotenuse is 9.

sin(b) = 4/9
{Make angle b the subject of the equation}
b = {sin}^{ - 1} ( \frac{4}{9} )
{Type this into the calculator}
Angle b = 26.4° (rounded off to 1 decimal place)

Hope this helps! :)

Please help. The correct and best answer gets brainiest! 29 points!!
attashe74 [19]

Answer:(15, 100)

Step-by-step explanation:

first find the coordinates of the point above (3, 20)

you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40

so the coordinate would be (6, 40)

now subtract (6, 40) by (3, 20)

6-3= 3

40- 20= 20

you get the first coordnites which is what you add (12,80) to

12 +3= 15

80+ 20= 100

you get the coordinates (15, 100)

A ladder reaches a window 20 feet above the ground. The foot of the ladder is 4 feet from the wall.
kobusy [5.1K]

Answer:

\sqrt{416} ft

or about 20.396ft when rounded to the third decimal place

Step-by-step explanation:

(assuming the question is to find the ladder's length)

let "l" be the ladder's length

20^{2} + 4^{2} = l^{2}

400 + 16 = l^{2} = 416

l = \sqrt{416} ft
