Plzz help me with the correct ans find x

Tresset [83]

Answer:

Step-by-step explanation:

Since, triangle ABC is the enlargement of triangle XYZ.

$\therefore \triangle ABC \sim \triangle XYZ$

So, corresponding sides of both the triangles would be in proportion.

$\therefore \frac{x}{6}=\frac{25}{10}$

$\therefore x= \frac{6\times 25}{10}$

$\therefore x =\frac{150}{10}$

$\therefore x = 15$

How do I solve x-y=11 2x+y=19

Margarita [4]

x-y=11 2x+y=19
x=11+y
2(11+y)+y=19
22+2y+y=19
3y=-3
y=-1
x=11-1=10

Please help! It would be very much appreciated :)

Trava [24]

Answer:

Cos 45=6/x

x=6/cos 45=6√2

x=6√2

tan 45=y/6

y=tan45 ×6

y=6

sin 60=y/10

y=sin60×10

y=5√3

again

Cos 60=x/10

x=½×10

x=5

Sin 45=x/5

x=1/√2×5 or

x=5√2/2

again

y=5√2/2 or 5/√2[base angle of right angled isosceles triangle]

Sin 30=8/x

½×x=8

x=8*2

x=16

again

cos 30= y/x

√3/2×16=y

y=8√3

sin 60=7/x

x=7/[√3/2]

x=14/√3 or 14√3/3

again

cos 60=y/x

½×14√3/3=y

7√3/2=y

y=7√3/2

Note:

Sin angle =perpendicular/hypotenuse

Cos angle =base/hypotenuse

Tan angle =perpendicular /base
