Since ten plus ten is twenty I think that x and y is ten
Answer:
angle C =160 degree
Step-by-step explanation:
since the given triangle is an isosceles triangle their base angles must be equal. So,
x - 10 =x/2
2(x - 10) =x
2x - 20 = x
2x - x = 20
x = 20
for angle B
x - 10
20 - 10
10 degree
for angle A
x/2
20/2
10
For angle c
angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)
10 + 10 + angle C =180
20 + angle C =180
angle C =180 - 20
angle C =160 degree
<span> If Jim has x football cards</span>
<span>He will have 5x baseballs cards</span>
Thus
<span> x + 5x = 120 >
total # of cards</span>
<span> 6x = 120</span>
<span> x= 120/6 =
20</span>
<span> so Jim has 5x
baseball cards = 20*5 =100 baseball cards</span>
