Angle sum of a triangle = 180°
Type of Triangle: Isosceles.
Therefore, 2 of the angles are equivalent.
2x = 50
2 ( 25 ) = 50
50 = 50
Meaning that the sum of the 2 angles is 100°.
( 5y + 10 ) + 2x + 50 = 180
5y = 180 - 100 - 10
5y = 70
y = 70 / 5
y = 14°
ANSWER:
y = 14°
Answer: Option A. 65 m^2
Solution:
Sides: a=10 m, b=14 m, c=20 m
Area: A=?
A=sqrt [p(p-a)(p-b)(p-c) ]
Semi-perimeter: p=(a+b+c)/2
p=(10 m+14 m+20 m)/2
p=(44 m)/2
p=22 m
A=sqrt [ (22 m)(22 m-10 m)(22 m-14 m)(22 m-20 m)]
A=sqrt [ (22 m)(12 m)(8 m)(2 m) ]
A=sqrt [ 4,224 m^4 ]
A=64.99230723 m^2
A=65 m^2
Answer:
PLATO: c. |t-48|</4
Step-by-step explanation:
You have to subtract 6y from both sides or subtract 7y from both sides(if you wanted to have a negative).
