Answer:
<h2>76</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>- triangles
- equation
- PEMDAS
- this is an isosceles triangle since two sides are equal therefore
- a triangle contains 180°
according to the question
2x+2+2x+2+3x+1=180
solve:
- collect like terms:7x+5=180
- substract 5 from both sides:=>7x+5-5=180-5=>7x=175
- divide both sides by 7: =>7x/7=175/7
- x=25
given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
