In geometry, there is a theorem that states: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside a circle is equal to half the difference of the measures of the intercepted arcs
Therefore, this problem has two secants, so m∠x= 1/2(141-25)
m∠x=1/2(116)
m∠x=58
Hope this helped :)
Hi, first, the grammar has been a bit confusing, but i think i have it. the question is that one group has 28 baseball cards and another has 68, right? in order to tell how much each person could have received, we first have to know how many people there were and divide the numbers of cards by that. since you never specified the number of people in the groups, i can't solve it completely. all together you have 96 cards. i hope this helps.
If x equals the number, then seven times the number is 7x; three less than that is 7x-3.
