Find the values of the variables! Please help! I’ll give brainliest to the first person :)))

b = 7 and a = 7

Step-by-step explanation:

This is because the angle across from 90 degrees equals 14. and this is a 30 - 60 - 90 triangle. therefore the unknown angle is 30 degrees. Which makes b half of the hypotenuse, or 14, so it becomes 7. and the side opposite to 60 degrees is root 3 times whatever b is. so a becomes 7 root 3. Hope this helps.

(-1,-0.5)

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
