In △ABC, m∠A=57°, m∠B=37°, and a=11. Find c to the nearest tenth.
kykrilka [37]

Answer:

c=13.1\ units

Step-by-step explanation:

step 1

Find the measure of angle C

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

so

A+B+C=180°

we have

A=57°

B=37°

substitute

57°+37°+C=180°

94°+C=180°

C=180°-94°=86°

step 2

Find the measure of side c

Applying the law of sines

\frac{a}{sin(A)}=\frac{c}{sin(C)}

substitute

\frac{11}{sin(57\°)}=\frac{c}{sin(86\°)}

c=\frac{11}{sin(57\°)}sin(86\°)

c=13.1\ units

In the figure at the right what is m < 1 if m < 3= 70 degrees
Arturiano [62]
<h2>○=> <u>Correct option</u> :</h2>

\color{plum}\tt\bold{(D)  \: 70}

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Angle 1 and angle 3 are vertically opposite angles.

We know that :

▪︎ Vertically opposite angles are always equal.

Which means :

Angle 1 = Angle 3

Thus, the measure of angle 3 = 70°

▪︎Therefore, the correct option is (D) 70

Solve for b.<br> 3-2(b-2)=2-7b3−2(b−2)=2−7b
lyudmila [28]

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1
