Question

the angles of triangle are P and Q and 40 degree the difference between the two angles P and Q is 30° find p and q

Answer 1

Answer:

P=85° and Q= 55°

Step-by-step explanation:

Given angles of triangle: P,Q and 40°

1st condition:

SUM OF ALL ANGLES OF TRIANGLE IS 180°

• P+Q+40°=180°

P+Q=180-40°

P+Q=180°......(i)

2nd condition;

Difference between P,Q is 30°

• P-Q=30°....(ii)

adding eq i and ii,We get;

P=85°

put P=85° in eq i,

u will get the value of Q

i.e. 55°

(for cross checking add the values of all angles: 85°+55°+40°=180°)

Hope it helps.,..
