Answer:

The triangles are similar

Step-by-step explanation:

You first flip the first triangle so the hypotenuse is facing the bottom right like the second triangle and the 49 degrees would be matching the same side as the picture would depict

You can then use the equaation 43 + 49 + x = 180 to solve for the missing angle in the second right triangle.

92 + x = 180

x = 88

The degrees match up, you then have to compare the sides.

You can first check the ratios between the same sides of the different triangles.

2.8 : 8.4

4 : 12

3.1 : 9.3

all of these ratios would be simplified to a 1:3 ration, meaning all the sides are proportional, making the triangles similar.

a) 3(-2) + 4(3) = -6 + 12 = 6

b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8

c) 4(-2) -(3) = -8 -3 = -11

d) -(-2) -2(3) = 4 -6 = -2

e) (1/2)(-2) +(3) = -1 +3 = 2

f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3

PLEASE HELP!

Answer:

Step-by-step explanation:

No because (1,2) falls on the line, and the line is a dotted line, which means that any point on the line is not a solution to the inequality.

I need help on my homework

Answer:

$\displaystyle m\angle AED=32.5^\circ$

Step-by-step explanation:

<u>Angles in a Circle</u>

An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.

Segments AE and DE are secants of the given circle. They form an exterior angle called AED.

The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.

Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:

$\displaystyle m\angle AED=\frac{AD-BC}{2}$

$\displaystyle m\angle AED=\frac{113^\circ-48^\circ}{2}=\frac{65^\circ}{2}$

$\displaystyle m\angle AED=32.5^\circ$

Someone explain how this is answer C? Big points!

Snowcat [4.5K]

Answer:

C. x = 15 * sin 18°

Step-by-step explanation:

sin A = Opposite / Hypotenuse

sin 18° = x / 15

x = 15 * sin 18°

gavmur [86]

Answer:

y=1/3x+1

Step-by-step explanation:

y=mx+b

y=1/3x+b

2=1/3(3)+b

2=1+b

1=b

y=1/3x+1
