Question

7. (a) In ∆EFG, ∠ E = 45° and ∠ F = 65°; find ∠G
(b) In ∆PQR, ∠P = ∠R = 60; find ∠Q

ANSWER ME FAST PLEASE BOTH ALSO

Answer 1

Answer:

180°. ⇒ 65° + ∠E + 45° = 180°. ⇒ ∠E = 70°

Step-by-step explanation:

Construct a Triangle of the Measures Given Below. in ∆Efg, L(Eg) = 6 Cm, M∠F = 65°, M∠G = 45° - Mathematics

Answer 2

Step-by-step explanation:

ACCORDING TO ANGLE SUM PROPERTY ;

SUM OF INTERIOR ANGLES = 180 °

In ∆ EFG ;

E = 45 ° ;

F = 65 °

G = ?

E + F + G = 180 °

45 ° + 65 ° + G = 180 °

110 ° + G = 180 °

G = 180 ° - 110 °

G = 70°

In ∆ PQR ;

P = R = 180 °

P + Q + R = 180 °

60 ° + 60 ° + R = 180 °

120 ° + R = 180 °

R = 180 ° - 120 °

R = 60 °
