Ответ:

9)Кут MLN = 50⁰

12) Кут AMN=90⁰; кутBMN = 90⁰

Объяснение:

9) кут TLR = кут KLT = 1/2 кута KLR

Кут TLR = 1/2 × 40⁰ = 20⁰

Кут RLM - прямий; кут RLM = 90⁰

Кут KLM - розгорнутий; кут KLM = 180

Кут MLN = кут KLM - (кут KLR + кут RLM)

Кут MLN = 180⁰ - (40⁰ + 90⁰) = 180⁰ - 130⁰ = 50⁰

12) кут AMC = кут DMB

Кут CMN = кут NMD

Кут AMB - розгорнутий; кут AMB = 180⁰ кутAMC+кутCMN+кутNMD+кутDMB=180⁰

2кутAMC+2кутCMN=180⁰

2(кутАMC+кутСMN)=180⁰

2кутAMN=180⁰

КутAMN=180⁰/2

КутAMN=90⁰

КутNMD= кутAMD - кутAMN = 180⁰- 90⁰= 90⁰
