Solve a triangle when A=15° B=113° and b=7?
JulsSmile [24]

Let us draw a triangle ABC with A=15° ,B=113° and b=7.

Please see the attached image.

We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have

A+B+C=180\\
\\
15+113+C= 180\\
\\
C=62^{\circ}

Apply Sine rule in the triangle ABC, we get

\frac{a}{\sin 15}= \frac{7}{\sin 113}\\
\\
a=\frac{7 \sin 15}{\sin 113}\\
\\
a=1.97\\
\\
\text{Again apply sine rule, we get}\\
\\
\frac{c}{\sin 62}= \frac{7}{\sin 113}\\
\\
c=\frac{7 \sin 62}{\sin 113}\\
\\
c=6.71

Therefore, we have

a=1.97\\
c=6.71\\
C=62^{\circ}

zzz [600]

Answer:

Devon have <u>70</u> points.

Step-by-step explanation:

Given:

Erin and Devon are playing a game. Erin has 42 points. If Devon had 14 more points, he'd have double the points Erin has.

Now, to find the points Devon have.

Let the points Devon have be x.

Erins has = 42 points.

<em>As, given if Devon had 14 more points, he'd have double the points Erin has.</em>

According to question:

x+14=42\times 2

x+14=84

Subtracting both sides by 14 we get:

x=70.

Therefore, Devon have 70 points.
