Answer:
<h2>76</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>tips and formulas:</h3>
- this is an isosceles triangle since two sides are equal therefore
- a triangle contains 180°
<h3>let's solve:</h3>
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
given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
Answer:
Hello,
le largest is <u>139</u>
Step-by-step explanation:
Since i am a lasy boy, i am going to calculate:
1+3+5+7+...+(1+2*59) there are 60 numbers
=1+3+5+..+119
=60*(1+119)/2=30*120=3600 (not enough)
4800-3600=1200 are in rest.
1200/60=20 so we add 20 to each number:
21+23+25+27+...+139=4800
