B=? Angle A=? Angle B=?

1.) Solve for length b.

The simpler method is to use the Pythagorean theorem. If a^2 - b^2 = c^2, then this means that c^2 - a^2 = b^2.

Plug in the values:

11^2 - 7^2 = b^2

--> 121 - 49 = 72

So this means that b is the square root of 72, which is 8.49

2.) Solve for ∠A.

Let's refer to the law of sines. If \frac{a}{sin(A)} = \frac{c}{sin(C)}, then this means we can cross multiply. Since A is the value we are solving for, the equation should be written out like this:

A = sin^-1(\frac{sin(C) * a}{c})

--> A = sin^-1(\frac{sin(90) * 7}{11})

A is 39.52°

3.) Solve for ∠B.

This is the easiest one. The sum of all three angle measures in a triangle add up to 180°. We already know that one of the angles is a right angle and the other 39.52°.

39.52 + 90 = 129.52

180 - 129.52 = 50.48

∠B is 50.48°.

Mike bought five items for lunch that cost a total of $4.55. Hot dogs cost $1.10 each and cookies cost $0.75 each. Which of thes
Setler79 [48]

Answer:

1.1h+0.75c=4.55---------------1

h+c=5--------------2

Step-by-step explanation:

Step one:

given data

total lunch items= 5

let hot dogs be h

and cookies be c

cost of hot dogs = $1.10

cost of cookies = $0.75

total cost = $4.55

Step two:

The linear model for the total cost is given as

4.55=1.1h+0.75c---------------1

and the model for the number of items is

h+c=5--------------2

The systems of the equation for the situation is

1.1h+0.75c=4.55---------------1

h+c=5--------------2
