Three angles of a quadrilateral are 34°, 70° and 126°. find the measure of the fourth angle.

130 will be correct answer

Step-by-step explanation:

The three angles are

34° 70° and 126°

we have to find fourth angle

let us consider fourth angle as X

The sum of quadrilateral is 360°.

So

34°+70°+126°+ x = 360°

130+X =360°

X = 360°-130°

X = 230°

Here we got the fourth angle

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
