Given: △ABC, m∠A=60° m∠C=45°, AB=8 Find: Perimeter of △ABC, Area of △ABC
Svet_ta [12734]

We are given the triangle

△ABC, with m∠A=60° and m∠C=45°, and AB=8.

To start, we will calculate all angles and sides.

Finding angle B:

The total of all angles in a triangle equals 180.

m∠A + m∠B + m∠C = 180.

Substituting the known values,

60° + m∠B + 45° = 180.

This gives us m∠B = 75°.

Calculating BC:

Using the law of sines,

\frac{AB}{sin(C)}=\frac{BC}{sin(A)}

We can substitute in the values.

\frac{8}{sin(45)}=\frac{BC}{sin(60)}

BC=\frac{8}{sin(45)} \times sin(60)

BC=9.798

Finding AC:

\frac{AB}{sin(C)}=\frac{AC}{sin(B)}

Now we'll input the values.

\frac{8}{sin(45)}=\frac{AC}{sin(75)}

AC=\frac{8}{sin(45)} \times sin(75)

AC=10.928

Calculating Perimeter:

p=AB+BC+AC

We substitute values here as well.

p=10.928+8+9.798

p=28.726

Calculating Area:

Using the area formula,

A=\frac{1}{2}AB \times AC \times sin(A)

we can then insert values.

A=\frac{1}{2}8 \times 10.928 \times sin(60)

A=37.85570...............Answer

Which of the following are true statements about a 30-60-90 triangle? Check all that apply.
Inessa [12570]

Answer:

C. The hypotenuse measures twice the distance of the shorter leg.

B. The longer leg is √3 times the length of the shorter leg.

Step-by-step explanation:

A 30-60-90 triangle is considered a right triangle. Triangles containing a right angle are classified as right triangles. Only one right angle can exist in such a triangle. The representation of this case is illustrated below. Let’s clarify why the proposed statements are valid:

The hypotenuse of a right triangle is always opposite to the right angle. If we designate a as the shorter leg, the sine law affirms that the hypotenuse is:

\frac{H}{sin90}=\frac{a}{sin30} \\ \\ \frac{H}{1}=\frac{a}{0.5} \\ \\ \boxed{H=2a}

This indicates that the hypotenuse is double the length of the shorter leg

The longer leg, which we can call x, can be determined with the Pythagorean Theorem:

H^2=x^2+a^2 \\ \\ x=\sqrt{H^2-a^2} \\ \\ x=\sqrt{(2a)^2-a^2} \\ \\ x=\sqrt{4a^2-a^2} \\ \\ x=\sqrt{3a^2}=\sqrt{3}a

Thus, it is accurate that the longer leg is √3 times longer than the shorter leg.

Miguel Rodriguez Borrowed $400 from his brother Julio to pay for books and tuition. He agreed to pay Julio in 6 months with simp
lawyer [12517]

Simple interest can be calculated using the formula:

S.I = P*T*R

Where S.I represents the simple interest to determine

P signifies the principal amount

T represents the time in years

R is the annual interest rate

In this instance:

The principal (P) is $400

The duration is 6 months, equivalent to 1/2 year

The annual interest rate is set at 6.8%, which is 6.8/100 or 0.068

Calculating Simple Interest gives us:

Simple Interest = P*T*R

Simple Interest = 400*1/2*0.068 = 200 *0.068

Simple Interest = $13.6

At the end of six months, Miguel must pay Julio $13.6 in interest.
