In the triangle below, suppose that mZA=(x+7), mZB=(4x+3)°, and mZC=(5x)" Find the degree measure of each angle in the triangle.
С
(5x)
o
mZA =
Х
m2 B = 1
m2C =
В B.
А
(4x + 3)
(x + 7)

your answer is b ^w^ hope i

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
