In step 2, you are adding 35.10 and 84.60. You carry the 1 to the 1's place after you add up the tenths and the hundreds place.
Answer: 12.32 is the answer.
Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.
We substitute in the values,
17^2+B^2=21^2.
Now we simplify.
289+B^2=441
We subtract the 289 from both sides,
B^2=152
Now we use square root to find the answer.
12.32 is the answer.
Hope this helps!
Well.. .not exactly what you're asking, but the relationship of them is

so... hmm to add some
for example let's say
Answer: B
Step-by-step explanation:
Because m<7 and m<6 share a vertex and doesn’t share any common sides and they are across from each other which means they are vertical and vertical angles are congruent
Subtract X
2y=-x+6
Then divide by 2
Y=-1/2x+3
