(All yes or no questions). Determine whether each of the following pairs of angles have equal measures:

a. KJLand LJM
b. MJP and PJR
C. LJP and NJR
d. MJK and PJR

Answer 1

9514 1404 393

Answer:

a) no

b) yes

c) yes

d) no

Explanation:

Angle LJM is complementary to KJL, so is ...

angle LJM = 90° -42° = 48°

Angle NJP is marked as congruent to angle PJQ, so is also 48°.

__

a) ∠KJL = 42° ≠ 48° = ∠LJM . . . . NO

b) ∠MJP = 46°+48° = 48° +46° = ∠PJR . . . . YES

c) ∠LJP = 48° +46° +48° = 48° +48° +46° = ∠NJR . . . . YES

d) ∠MJK = 90° ≠ 48° +46° = ∠PJR . . . . NO
