Answer:

<h2>The measure of angle B is 46.4°, approximately.</h2>

Step-by-step explanation:

We need to find the measure of angle B. Notice that it's a right triangle, where we already know the hypothenuse and the adjacent leg to the angle, that means we need to use the cosine trigonometric reason

$cosB=\frac{adjacent}{hypothenuse}=\frac{20}{29}\\ B=cos^{-1}(\frac{20}{29}) \\B \approx 46.4 \°$

Therefore, the measure of angle B is 46.4°, approximately.

Please help me with question 3

Set up a proportion.
24/x=9/15
24(15)=9x
360=9x
40=x

x=40

This is because if side one of the smaller triangle is 9 and side two of the smaller triangle is 15, and if side one of the larger triangle is 24 then side two of the larger triangle has to be 40 because they are proportional.

I hope this helps!
Best wishes :)

The end points of a diameter of a circle are (6,2) and (-4,7).

nata0808 [166]

Answer:

Step-by-step explanation:

The standard form equation of a circle with radius r is expressed as

( x − h )^2 + ( y − k )^2 =r ^2 ,

where r represents the radius

h and k are the coordinates of the center of the circle C( h , k )

To determine the coordinates at the center of the circle, the midpoint formula would be used. It is expressed as

[(x1 + x2)/2 , (y1 + y2)/2]

Midpoint of the circle =

(6 - 4)/2 , (2 + 7)/2 = (1, 4.5)

h coordinate of the center = 1

k coordinate of the center = 4.5

r^2 = (x - h)^2 + (2 - k)^2

r^2 = (6 - 1)^2 + (2 - 4.5)^2

r^2 = 5^2 + (- 2.5)^2 = 25 + 6.25

r^2 = 31.25

Substituting r^2 = 31.25, h = 1 and k = 4.5 into (x − h )^2 + ( y − k )^2 = r^2, the standard equation of the circle becomes

(x − 1 )^2 + ( y − 4.5 )^2 = 31.25

Round each time to the nearest whole second. Then estimate how many seconds bailey won the race by.

Orlov [11]

The whole second is the first number to the left of the decimal (_.), so : 35.78=36 because 7>5. 39.51=40 because 5=5. 40-36=4. Bailey won the race by about 4 seconds. Hoped I helped!
