Answer:
Mark has 6 times as many as Tom
Step-by-step explanation:
Elijah = E
Tom = T
Mark = M
Translate the information into mathematical equation :
E = 3T
M = 2E
How many times Mark has as many as Tom ?
M = ..... T ?
M = 2 E (Remember, E = 3T, insert this)
M = 2 ( 3 T )
M = 6 T
Mark has 6 times as many as Tom
Since a triangle's angles add to be 180 degrees, you need to find the measure of the third angle.
180-55-65= 60 degrees
