Use the figure to the right to find the missing lengths of the triangle. ac = 7 cm; find ab and bc. triangle a b c has legs a c and b c, a hypotenuse a b and is labeled as follows: a, 60 degrees; b, 30 degrees; c, right angle.

To find AB(x) and BC(y), you can do(there are multiple ways you can do this):

tan A =

tan 60° = or (tan 60°) · 7 = y

tan 60° =

√3 · 7 = y

7√3 cm = y

sin B =

sin 30° = or

sin 30° = =

x =

x = 14 cm

AB = 14cm

BC = 7√3 cm

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
