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
76

The number students is = 95
The number of teachers is = 5
<em><u>b. 280 people </u></em>
Ratio = 19 : 1
The sum of the ratio is 19 + 1 = 20
Scale factor =
scale factor = 14
The number students is = 266
The number of teachers is = 14
<em><u>c.440 people</u></em>
Ratio = 19 : 1
The sum of the ratio is 19 + 1 = 20
Scale factor =
scale factor = 22
The number students is = 418
The number of teachers is = 22
<em><u>d.760 people</u></em>
Ratio = 19 : 1
