Find y if x=15 if y is 6 x=30

1 answer:

I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?

If so then y = 120

The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.

Use the figure to the right to find the missing lengths of the triangle.

pychu [463]

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

tan A = $\frac{y}{7}$

tan 60° = $\frac{y}{7}$ or (tan 60°) · 7 = y

tan 60° = $\frac{\frac{\sqrt{3} }{2} }{ \frac{1}{2} } = \sqrt{3}$

√3 · 7 = y

7√3 cm = y

sin B = $\frac{7}{x}$

sin 30° = $\frac{7}{x}$ or $x= \frac{7}{sin 30}$

sin 30° = $\frac{\frac{1}{2} }{1}$ = $\frac{1}{2}$

x = $\frac{7}{\frac{1}{2} } = 14$

x = 14 cm

AB = 14cm

BC = 7√3 cm

Use addition properties and strategies to find the sum..1.)34+62+51+46=? 2.)27+68+43=? 3.)42+36+18=? 4.)74+35+16+45=?

erica [24]

1.
$34 + 62 = 96 + 51 = 147$
$147 + 46 = 193$

2.
$27 + 68 = 95 + 43 = 138$
3.
$42 + 36 = 78 + 18 = 96$
4.
$74 + 35 = 109 + 16 = 125 + 45 =$
$= 70$
