Step-by-step explanation:
a) The circumference of a circle is 360 degrees. so:
7x+15+8x+6x+30=360
21x+45=315
21x=135
x=<u>15</u>
b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.
Answer:the ration to x and b that equals c is about 3 dollars
Step-by-step explanation:
Answer: 5 7/10
Step-by-step explanation:
2 is the only number (other than 1, but in most cases 1 does not count) that goes into both 48 and 46.
48 / 2 = 24
46 / 2 = 23
Because of the fact that 48 and 46 are only two numbers apart, it would be impossible for any number greater than two to divide evenly into both.
Let thw second integer be x
then the first = 2x
and the third integer is = 6+x
their sum = 74
x+2x+6+x = 74
4x +6 = 74
4x = 74-6 =68
x =68÷4
x = 17
then the first integer is 2×17 = 34
the third integer is 17+6 = 23
the integers are 17 , 23 and 34
