Answer:
none of these triangles are similar
Step-by-step explanation:
for a triangle to be similar, they have to have the same angle measures
Answer:
multiply 2 with the parenthesis
19-2m<7+8m-8
then you put a dot between -2 amd 3
Step-by-step explanation:
The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.
3 x 2.7 is the same as 3 x 3 x 0.9 = 9 x 0.9 = 8.1
