Answer:

D

Step-by-step explanation:

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

\frac{AD}{CD} = \frac{BD}{AD} , substitute values

\frac{x}{13} = \frac{3}{x} ( cross- multiply )

x² = 39 ( take the square root of both sides )

x = \sqrt{39} → D

Answer:

The value of a is 50°.

Step-by-step explanation:

In an isosceles triangle, 2 sides have the same lengths and same angles so we can assume that the other side of the triangle is 65°.

Given that the total angle of a triangle is 180°, so have to subtract it :

a = 180 - 65 - 65

a = 180 - 130

a = 50

2x - 5y = 16<br> x - 2y = 5<br> elimination?
harina [27]

Answer:

Y = 6

X = 24

Step-by-step explanation:

2x -5y = 16

(x -2y =5)*2

_______________

2x -5y = 16

2x - 4y = 10

_______________

(2x -5y = 16) - (2x - 4y = 10)

_______________

0x -y = 6

_______________

y =6

_______________

Replacing in equation 1:

2x - 5(6) = 16

so, 2x = 16 + 30

2x = 48

x = 24
