28°, 93° and 59°
let x be the first angle then the second angle = 3(x + 3)
and the third angle = 2x + 3
the sum of the angles in a triangle = 180° , thus
x +3x + 9 + 2x + 3 = 180
6x + 12 = 180 ( subtract 12 from both sides )
6x = 168 ( divide both sides by 6 )
x = 28
the angles are x = 28° , 3(x + 3 ) = 93° and 2x + 3 = 59°
Answer:
m<A = 36 degrees
Step-by-step explanation:
we know that the top angle is 90 degrees and so (x+46) + (x + 66) = 90
simplify and we get 2x + 110 = 90
x = -10
substitute -10 for x
m<A = (-10) + 46
m<A = 36
Answer:
j = $7.38 / 18
Step-by-step explanation:
1. We have to find the total cost of a 18 juice bottles pack
= $ 9.63 - $ 2.25
= $ 7.38
2. To find how much each bottle of juice costs :
j = $ 7.38 / 18 #
Answer:
1.the sum of three consecutive odd number is 177 find the number
let three consecutive odd number be x,x+2&,x-2.
by question
answer
x+x-2+x+2=177
3x=177
x=177/3=59
x-2=59-2=57
x+2=59+2=61
required no are 59,57&61
2. find three consecutive even
number which add 1524
answer
let three consecutive even
number be x-2,x+2&x
by question
x-2+x+2+x=1524
3x=1524
x=1524/3=508
x-2=508-2=506
x+2=508+2=600
required no are 508,506&600
3.when a number is doubled and the added to 13 the result is 3.8 find the number
answer
let no be x
by question
2x+13=3.8
2x=3.8-13
x=-9.2/2=-4.6 is the required number
