Answer:

C. 42° and 48°

Step-by-step explanation:

Complementary angles: Angles that add up to 90°.

So we can set up an equation..

(x + 3) + (x + 9) = 90

2x + 12 = 90

2x = 78

x = 39°

Now we can find the angles.

Angle 1:

(x + 3)

= 39 + 3

= 42°

Angle 2:

(x + 9)

= 39 + 9

= 48°

And we can check to see if they add to 90°,

42° + 48° = 90°

9.01 prove that the two circles are similar
il63 [147K]

Answer:

see the procedure

Step-by-step explanation:

we know that

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another.  

In this problem to prove circle C and circle A are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

we have that

Circle C is centered at (0,-1) and has a radius of 2 units

Circle A is centered at (3,4) and has a radius of 5 units

step 1

Move the center of the circle C onto the center of the circle A

the transformation has the following rule

(x,y)--------> (x+3,y+5)

so

(0,-1)------> (0+3,-1+5)-----> (3,4)

center circle C is now equal to center circle A  

The circles are now concentric (they have the same center)

step 2

A dilation is needed to increase the size of circle C to coincide with circle A

scale factor=radius circle A/radius circle C-----> 5/2=2.5

radius circle C will be=2*scale factor-----> 2*2.5=5 units

radius circle C is now equal to radius circle A  

therefore

A translation, followed by a dilation will map one circle onto the other, thus proving that the circles are similar

PLEASE HELP ME I'M STUCK ON THIS QUESTION!!!!!!!!!!!!!!!!!!!!!!

We wish to know how much faster Grant rows than Arianna.

d=G-A  and we want our answer is miles/hour so

d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)

d=10mph-6mph

d=4mph

So Grant rows 4 miles per hour faster than Arianna.

No links please just answers thank you

Answer:

1. If x = 4 and y = 8, u = 3x - 4 would make sense because 3x, or 3 x 4 = 12

12 - 4 = 8 y = 8 (True)

2. m = 12 and n = 200 . n = 15m - 20 15 x 12 = 180 180 - 20 = 200 Would not make sense because 180 - 20 is 160 (False)

3. a = 5 and b = 48    b = 48 . 8a + 8 = 8 x 5 + 8 8 x 5 + 8= 48

(True)

4. G = 40 and h = 1000

H = 25g + 300

25g = 1000

1000+300= 1300, not 1000

(false)
