The sum of the two angles of the parallelogram is 170 ° to determine the other angles

Konichiwa (hi in japanese , as im clearly an anime fan)

anyways,

We know that, the sum of all angles of a parallelogram = 360°

So, let all the angles be angles P, Q, R and angle S.

Let, <P + <Q = 170°

So, <P + <Q + <R + <S = 360°

=> 170° + <R + <S = 360°

=> <R + <S = 360°-170° = 190° (Ans.)

So, the sum of other two angles becomes 190°

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
