1/2 x 5/8 = 20/8 = 5/2
3/5 x 5/8 = 600/40 = 15
3/8 x 2/5 = 240/40 = 6
Answer:
60 000 100 = 60 000 000 + 100
(7x -7) + (6x +6) = 90
take away the parenthesis: 7x - 7 + 6x + 6 = 90
combine like terms: 13x - 1 = 90
add 1 to both sides: 13x = 91
divide both sides by 13: <span>x = 7.
Now: substitute x = 7 into the angles: the first angle is 42 degrees, the second angle is 48 degrees</span>
Answer:
7.74cm ^2
Step-by-step explanation:
a=pie * r ^2
3.14*3^2=3.14*9=28.26 then you know all sides of a square are equal and 3 is half of 1 side so 6*6-=36 36-28.26=7.74
Size got it right because it’s multiplied by 100
