Answer:

The answer is 79 degrees

Step-by-step explanation:

Vertically opposite angles are exactly the same. In this case M<AED and M<IEF are vertically opposite from each other.

In △ABC, m∠A=52°, c=11, and m∠B=19°. Find a to the nearest tenth.

Ugo [173]

From the problem we have

In △ABC, m∠A=52°, c=11, and m∠B=19°.

Draw the diagram with the help of given information, (see the attached image)

Now using Sine Law in the Triangle ABC, we can write

Now from Triangle ABC , we can write

$\frac{a}{sin52}=\frac{11}{sin109} \\$

Now simplify , we get

$\Rightarrow a=\frac{11}{sin109}*sin52\\ \\ \Rightarrow a=\frac{11}{0.9455}*0.7880\\ \\ \Rightarrow a=9.1676 \approx 9.2\\$

What is the length of BC?

ELEN [110]

Answer:

Step-by-step explanation:

3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
2x - 15 = 33 [subtract x from both sides]
2x = 48 [add 15 to both sides]
x = 24 [divide both sides by 2]
BC = 24 [BC = x]
