Question

ABC is a right angles of an equilateral triangle in which angle A is equal to 90 degree and AB=AC . Find angle B and angle C​

Answer 1

Answer:

angel b=45 and angle c=45

Step-by-step explanation:

in ABC

• A+B+C= 180
• 90 +B + C=180 (AB= BC. , So angel B =angel C)
• 90+B+B=180
• 2B=180 - 90
• 2B= 90
• B = 90 ÷ 2
• B = 45

NOW,,,

angel A = 90

angel B = 45

angel c =45
