6. The triangle is acute

m<P = 60

m<Q = 84

m<R = 36

7. Claim: the three angles added together equal 180 degrees

m<J = 116 degrees

m<K = 33 degrees

m<L = 38 degrees

Step-by-step explanation:

m<P = 4a + 12 = 4(12) + 12 = 60

m<Q = 7a = 7(12) = 84

m<R = 3a = 36

(4a + 12) + 7a + 3a = 180 degrees

14a + 12 = 180

14a = 168

a = 12

m<J = 4x + 12 = 4(26) + 12 = 116

m<K = x + 7 = 26 + 7 = 33

m<L = 2x - 14 = 2(26) - 14 = 38

(4x + 12) + (x + 7) + (2x - 14) = 180 degrees

7x - 2 = 180

7x = 182

x = 26
