Step-by-step explanation:
remember : the sum of all angles in a triangle is always 180 degrees.
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C) with the sides being always opposite of the angles.
so,
the opposite angle of x is
180 - 90 - 58 = 32 degrees.
x/sin(32) = 11/sin(58)
x = 11×sin(32)/sin(58) = 6.873562871...
rounded x = 6.9
25 less than or equal too 300,not really enough information
Is this a multiple choice
D)42 because u first have to multipy left to right then divide left to right then do the same thing with add and subtract
X+y=20
xy=99
Let a+b be denoted a,b
20 = 1,19 2,18 3,17 4,16 5,15, 6,14 7,13 8,12 (9,11) ..Stop
99=3^2*11
Thus the ages are 11 and 9 with a difference of 2.
