Answer:
x = 105 degrees
Step-by-step explanation:
First, figure out the interior angle, we can do this ading the two angles and then subtracting the sum from 180 (since the interior angle of a triangle adds up to 180 degrees)
180 - (55 + 50) = 75
next, we can figure out x by taking the sum (75) and subtracting that from 180 since it is a supplementary angle:
180 - 75 = 105
x = 105
Step-by-step explanation:
First you need to find the semi perimeter (s) and apply the formula of the triangle and you will get your answer
Answer:
Step-by-step explanation:
15/2=75/x
Cross multiply
15x=150
x=10
