f(1) = 2; f(n) = f(n-1) + 7

f(2) = (2-1) + 7 = 1 + 7 =8

f(3) = (8-1) + 7 = 7 + 7 =14

f(4) = (14-1) + 7 = 13 + 7 =20

f(5) = (20-1) + 7 = 19 + 7 =26

and so on...so it's increase by 6

f(6) = 26 + 6 = 32

f(7) = 32 + 6 = 38

f(8) = 38 + 6 = 44

f(9) = 44 +6 = 50

f(10) = 50 + 6 = 56

What is value of x? <br> See picture

morpeh [17]

Answer:

x = 71

Step-by-step explanation:

Since 2 sides of the triangle are congruent then the triangle is isosceles.

Thus the 2 base angles are congruent

The sum of the 3 angles in the triangle = 180°, so

x = $\frac{180-38}{2}$ = $\frac{142}{2}$ = 71
