X=12 because you would sub the 3 on both sides
Answer:
4n=c
Step-by-step explanation: i took the quiz if this is wrong its prob a differnt
quiz the last person i answered got md at befor i didnt know what quiz she take a.
Lets x = missing angle
x = 180 - (60+80)
x = 180 - 140
x = 40
answer
40
The measure of the angle B is 30 degree after applying the sin law of triangle.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle shown in the picture:
We can apply the sin law of the triangle to find the angle B
SinB = 0.499
B = 29.99 ≈ 30 degree
Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.
