Answer:
In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.
Answer:
Option d.
Step-by-step explanation:
For this problem we have 2 sides of a triangle (a and b) and the angle between them C = 160 °.
We have a triangle of type SAS.
We have:
a=25
b=30
C= 160°
Then we use the law of cosine.
Now we substitute the values in the formula to find c
Now we use the cosine theorem to find B. (You can also use the sine)
Finally:
Answer:
Im dumb but cant you just be like, I subtracted 146° and 62°?
59+61+63 is a possibility
