X = 42 - 19, so A - x = 23
D. -2p + q - 5 - you have to multiply, then distribute parentheses and apply plus or minus rules.
Answer:

Step-by-step explanation:
Given:
KL ║ NM ,
LM = 45
m∠M = 50°
KN ⊥ NM
NL ⊥ LM
Find: KN and KL
1. Consider triangle NLM. This is a right triangle, because NL ⊥ LM. In this triangle,
LM = 45
m∠M = 50°
So,

Also
(angles LNM and M are complementary).
2. Consider triangle NKL. This is a right triangle, because KN ⊥ NM . In this triangle,
(alternate interior angles)
(angles KNL and KLN are complementary).
So,

and

ANSWER:⇒ ⁶¹/₂₀
Can also be wrote out like:⇒ 3.05, 3¹/₂₀
Formulate & Calculate:
⁶¹/₄ × ₅
Calculate the product or quotient:
⁶¹/₂₀
