Find the measure of angle Need help
A.
1150
16
A
A) 130°
C) 80°
B) 40°
D) 35°

180-115=165°

Total angle of a triangle is 180 and we already know one angle so lets minus it from 180-165=115°

So we know that the other two angles must equal to 115.

Since both of the missing variables have 'x', they are considered to be like terms so we can add them together.

7+16=23

The equation now becomes; 23x=115

To get 'x', we must move the variable kn front of x ro the other side of the equation. Since the left side of the equation is multiplication, we divide on the other side.

x=115/23

Therefore x = 5

If x = 5 and we're trying to solve for A, we substitute x into the expression.

A=7x

A=7(5)

A=35

ANSWER IS 35°

Hopefully this helped !! have a nice day :)

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

250
