Determine the number of possible triangles, ABC, that can be formed given A = 30°, a = 7, and b = 18.
zzz [600]

Answer:

none

Step-by-step explanation:

We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.

According to the 'Law of Sines- Ambiguous Case', we have,

If a < b×sinA, then no triangle is possible.

If a = b×sinA, only one triangle is possible

If a > b×sinA, two triangles are possible.

So, we have,

b×sinA = 10 × sin30 = 10 × 0.5 = 5.

Now, as

4 = a < bsinA = 5.

We get, according to the rule, no triangle is possible.

astraxan [27]

Answer:

x= 1

y= -1

Step-by-step explanation:

y=-2x+1

2x-2y=4

substitute for y

2x-2(-2x+1)=4

reduce

2x+4x-2=4

6x=6

x=1

y= -2(1)+1

y= -1

Step-by-step explanation:

Assuming you mean

f(x) = 1/(x-3)

The domain is all numbers that x can take

This function is define except when the denominator goes to zero

x-3 cannot be zero

x cannot be 3

Jennifer makes 1.7 liters of lemonade. If she pours 3 tenths of the lemonade in a glass, how many liters of lemonade are in the
Akimi4 [234]

Answer:

0.51 liters in the glass

Step-by-step explanation:

Given

Litres = 1.7L

Pour= \frac{3}{10}th

Required

Determine how many liters in the glass

To do this, we simply multiply the fraction poured by the total.

So, we have:

Poured = \frac{3}{10} * 1.7

Poured = \frac{3* 1.7}{10}

Poured = \frac{5.1}{10}

Poured = 0.51

<em>There will be 0.51 liters in the glass</em>
