Given ∆qrs ~ ∆Xyz, what is the value of tan(q)

alexandr402 [8]

We know that

in the triangle QRS
tan Q=RS/SQ

in the triangle XYZ
tan X=YZ/ZX---------> tan X=9/12------> tan X=3/4

so
<span>∆qrs ~ ∆Xyz
</span>tan Q=tan X----------> tan Q=3/4

the answer is
tan Q=3/4

Answer:

b = 12

Step-by-step explanation:

c^2 = a^2 + b^2

Solving for b,

b^2 = c^2 - a^2

= (13)^2 - (5)^2

= 169 - 25

= 144

or

b = 12

Can someone please solve for x

RoseWind [281]

Answer:

x = -11

Step-by-step explanation:

2x + 23 + 9 = x + 21

Combine common factors

2x + 32 = x + 21

Subtract x from both sides

x + 32 = 21

Subtract 32 from both sides

x = -11
