Which statement is true about the angles?
liq [111]

Complete Question:

Triangle abc has the angle mesausres shown.

m<A = (2x)°

m<B = (5x)°

m<C = (11x)°

Which statement is true about the angles?

A. m<A = 20°

B. m<B = 60°

C. m<A and m<B are complementary

D. m<A + m<C = 120°

Answer:

A. m<A = 20°

Step-by-step explanation:

m<A + m<B + m<C = 180° (sum of interior angles of a triangle)

2x + 5x + 11x = 180 (substitution)

Solve for x. Add like terms.

18x = 180

Divide both sides by 18

\frac{18x}{18} = \frac{180}{18}

x = 10

Find the measure of each angle by substituting x = 10:

m<A = (2x)° = 2(10) = 20°

m<B = (5x)° = 5(10) = 50°

m<C = (11x)° = 11(10) = 110°

Therefore, the only true statement is:

A. m<A = 20°

In the binomial probability​ formula, the variable x represents the​ _______. In the binomial probability​ formula, the variable
wolverine [178]

Answer: Option 'A' is correct.

Step-by-step explanation:

In the binomial probability formula, we have

P(X=x)=^nC_xp^{x}q^{n-x}

Here, n = number of events

x = number of trials

p = probability of success

q = probability of failure

x is the number of trials among which we decide the number of successes and number of failures.

So, Option 'A' is correct.

How would you create a system of linear equations to solve using substitution for this problem?
tino4ka555 [31]

we have

x ----> number of hats the sold

y ----> number of scarves they sold

so

12x+15y=690 ------> equation A

y=x+10 -----> equation B

Solve the system of equations

Using substitution Method

substitute equation B in equation A

12x+15(x+10)=690

solve for x

12x+15x+150=690

27x=690-150

27x=540

x=20

Find out the value of y

y=x+10

y=20+10

y=30

therefore

The answer is

<h2>20 hats and 30 scarves</h2>

Perform the indicated multiplication below. Reduce terms and simplify. Include all of the necessary steps and calculations in yo
Andre45 [30]
Complex numbers multiplication is commutative.
so 

given 
= (2+i)(1+2i) * (3-i)(3+i) * (1-i)

|(2+i)(1+2i)| has 5 as its absolute value and geometrically thinking its argument is pi/2. so

(2+i)(i+2i) = 5i

and obviously 

(3+i)(3-i) = 10

so the answer is 

50i * (1-i) = 50 + 50i

maybe, I think...
