C because this is the only triangle that has a non included angle leaving 145 degrees to create another triangle
2b + 6
2(b+3)
if you distribute 2(b+3), you get 2b+6
Answer:
cos B
Step-by-step explanation:
Let us take a look at angle B
The side adjacent angle B is 24 while the hypotenuse (the side facing the right angle) is 25
The relationship between the adjacent and the hypotenuse can be mapped our using the cosine
So, the cosine is the ratio between the adjacent and the hypotenuse
Hence, cos B = 24/25
