Given the measures a = 10, b = 40, and A = 30°, how many triangles can possibly be formed?
arlik [135]

Answer:

no triangle can be formed with the given values (i.e 0 triangle).

Step-by-step explanation:

Given;

length of side a, = 10

length of side b, = 40

angle A, = 30°

Apply sine rule to determine the angle of the second side (B);

\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2

The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

Connor spent $66 on rookie cards and Hall of Fame cards how many of each type of car did he buy rookie cards are four for six Ha
barxatty [35]

Answer:

We conclude that he purchased 20  rookie cards and 8  Hall of Fame cards.

Step-by-step explanation:

We know that Connor spent $66 on rookie cards and Hall of Fame cards. We know that rookie cards are four for six Hall of Fame two for nine.

Therefore, we calculate:

5\cdot 6 +4\cdot 9=30+36=66

5·4= 20 rookie cards

4·2= 8 Hall of Fame cards

We conclude that he purchased 20  rookie cards and 8  Hall of Fame cards.

X over 2x+1. What is x?
tatiyna

Answer:

x= - \frac{1}{2}

Step-by-step explanation:

Given:

\frac{2x+1}{x}

Let us assume that this equation is equal to 0.

Hence \frac{2x+1}{x}=0

Now Solving the above equation we get,

\frac{2x+1}{x}=0\\\\2x+1=0\\2x=-1\\x= - \frac{1}{2}

Hence by solving the equation we get x= - \frac{1}{2}
