The two angles are vertical from each other, we know this because they are directly across from one another
A = base * height
A = 10 *17
A =170
170 is the correct answer
70
7x10=70
So 1/10 of 70 is 7
Answer:
61 degrees
Step-by-step explanation:
87+32=119
180 (total degrees for triangle)-119=67 degrees
Answer:
so this uses proportions.
you need to find the side BF which is proportional to the side BF.
You do:
9/6=x/42
and cross multiply
9*42=6*x
378=6x
divide by 6 on both sides
x=63
the answer is 63
