Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal
(a)
=
, substitute values
=
( cross- multiply )
7.2XZ = 117 ( divide both sides by 7.2 )
XZ = 16.25 cm
---------------------------------------
(b)
=
, substitute values
=
( cross- multiply )
18QR = 122.4 ( divide both sides by 18 )
QR = 6.8 cm
It means if A=21 them B is also =21
Answer:
Sorry for being late it is 3.5 Or In a mixed Fraction 3
Step-by-step explanation:
I took the test Hope this helps :D
2.5-2.1=0.4
41+51=92
0.4x2+92x2=184.8 units
(x-2)(x+10)=13
x^2 + 10x - 2x - 20 = 13
x^2 + 8x - 20 - 13 = 0
x ^2 + 8x - 33 = 0
(x + 11) (x - 3) = 0
x + 11 = 0
x = -11
x - 3 = 0
x = 3
The answer is clearly x = 3.
Choice a.
