We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26

Answer:
17 years.
Step-by-step explanation:
Zanna was born is 1997
Zanna's cousin was born in 1980
1997 - 1980 = 17
Z is congruent to X because they are across from each other on the triangle, so angle z is 30°. hope this helped, please give brainliest
Answer:
Total Area = Area of Triangle + Area of Semicircle
Total Area = 1/2(bh) + 1/2(pir^2)
Total Area = 1/2(120) + 1/2(3.14(36))
Total Area = 60 + 18(3.14)
Total Area = 116.52
