Answer:
Well the answer is 13.3 so 13 years old
Step-by-step explanation:
(F,Y) = (63,21)
Y3=F so F/3=y
so
F= 40
Y=?
40/3=Y
40/3=13.3
If you are given with all the tree sides of the triangle, you may solve for all the angles through the Law of Cosines,
c² = a² + b² - 2ab(cos C)
where angle C is the angle opposite the side c. You may use the same equation to get the values of the remaining angle. Additionally, if you already have one known angle, you can solve for the rest of the angles by Law of Sines,
a / sin A = b / sin B = c / sin C
Answer:
first box is 4/5 and the second box (=) is 7/15
Use the property that angles sum up to 360 degrees.
Also use property that <M = <R and <A = <P.
That gives the following equation:
m<R + m<A + m<M + m<P = 360
6x+5 + 9x+25 + 6x+5 + 9x+25 = 360
30x + 60 = 360
x = 10
Answer:
x = 10
m<M = 6x+5 = 65 degrees
