Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
STEP BY STEP BREAK DOWN.
rewrite the equation to g/8=5
multiply both sides by 8
cancel the common factors (cancel both 8s)
rewrite g=8 x 5
solve 8 x 5 (equals 40)
g=40
25 times 8.14 is $203.50 so there’s your answer
It would be better if you've attached the figure its angle I should calculate. But I'll help you with some advice. You can find application in the internet that will calculate any angle by different ways. Just search your question, it will be first link
