Answer:
9.103
10. 77
11.60
12. 6.4
13. 20
14. 36
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
180 - (47 + 30) = 103
DEG = 180 - 103 = 77 angles on a straight line equals 180
An equilateral triangle has all 3 sides equal
if the sum of angles in a triangle is 180 degrees, each angle measures 180 / 3 = 60
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
5² + 4² = 41
squareroot of 41 = 6.4
b : √(25² - 15²) = 20
√(60² - 48²) = 36

76.72135955 is the answer I think So if the answer is correct then plz mark me as brainliest
Answer:
7(7x-4)
Step-by-step explanation:
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
49x -28
7(7x-4)
34/4=17/2
~~~~~~~~
34:2=17
4:2=2
Have a nice day!! ^^
