(6) Given that in ΔPQR, m∠P = (x+14)°, m∠Q = (6x-12)° and m∠R = (3x+8)°
We need to determine the value of x.
<u>Value of x:</u>
By triangle sum property, we have;
Substituting the values, we get;
Thus, the value of x is 17
(7) Given that ΔGHI, m∠G = (4x+13)°, m∠H = (8x-52)° and m∠I = (2x+4)°
We need to determine the measure of ∠G
<u>Value of x:</u>
By triangle sum property, we have;
Substituting the values, we get;
Thus, the value of x is 12.
<u>The measure of ∠G:</u>
Substituting x = 12 in m∠G = (4x+13)°, we get;
Thus, the measure of angle G is 61°
