Answer:

19. x=28°

<E = 67°

20. x= 9°

<L = 25°

Step-by-step explanation:

19. Supplementary means that the angles will add to make a straight line, or they will add to = 180

<L+<E = 180°

4x+1°+3x-17°=180°

7x-16°=180°

7x=196°

x=28°

Measure of Angle E

<E = 3x-17° = 3(28°)-17° = 67°

20. Vertical angles are congruent, or equal to each other.

<L = <E

2x+7° = 4x-11°

2x+18° = 4x

18° = 2x

9° = x

x = 9°

<L = 2x+7° = 2(9°)+7° = 18°+7° = 25°

What is the equation of a circle centered at the origin with radius 20

Nadya [2.5K]

Answer:

we have a rule

(x-h)²+(y-v)²=r²

while h is the x intercept

v is y intercept

r is the radius

so the answer will be

x²+y²=400

x²+y²=20²

A box is filled with 2 blue cards, 4 brown cards, and 6 yellow cards. A card is chosen at random from a box. What is the probabi

Finger [1]

Answer:

Therefore the probability that the card is not brown is $\frac12$ .

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

$Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}$

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

$=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}$

$=\frac{6}{12}$

$=\frac12$

∴P(not getting a brown card)

=1 - P(getting a brown card)

$=1-\frac12$

$=\frac12$

Therefore the probability that the card is not brown is $\frac12$ .

What's the circumference of a<br> circle with a diameter of 9 inches?<br> Use 3.14 for n.

Rainbow [258]

Answer:

28.26 in

Step-by-step explanation:

Radius = (1/2) diameter

Radius = (1/2)(9)

Radius = 4.5 in

Circumference = 2πr

Circumference = 2(3.14)(4.5)

Circumference = 28.26 in
