Answer:

X = 24

Step-by-step explanation:

Since the two triangles are similar such that one is twice the other, twice of 9 is 18; and thus twice of 12 equals 24.

Answer:

x = 20

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{x}{12}$ = $\frac{15}{9}$ ( cross- multiply )

9x = 180 ( divide both sides by 9 )

x = 20

What is the measure of PSQ in degrees? Angle PSR measures 99°.

11111nata11111 [884]

we know that

Step 1

Find the value of x

m∠PSR= $99$ °

m∠PSR= $(3x+18)+(9x-27)$ °

$99 =(3x+18)+(9x-27) \\ 99=12x-9\\ 12x=108\\ x=9degrees$

Step 2

Find the value of m∠PSQ

m∠PSQ= $(3x+18)$

m∠PSQ= $(3*9+18)$

m∠PSQ= $45$ °

therefore

the answer is the option

C) 45 degrees

1/2+1/4=____ and 1/12 + 1/6=___ and 1/4+1/6+1/12=_____ . explain

BlackZzzverrR [31]

1/2+ 1/4
= 2/4+ 1/4
= 3/4

1/12+ 1/6
= 1/12+ 2/12
= 3/12
= 1/4

Therefore, 1/4+ 1/6+ 1/12
= (1/12+ 1/6)+ (1/12+ 1/6)
= 2*(1/12+ 1/6)
= 2* (1/4)
= 2/4
= 1/2

Hope this helps~
