Answer:

x = 59°

Step-by-step explanation:

The angle marked 115° and the angle that is the sum of angles x and 56° are alternate interior angles, so have the same measure:

115° = x +56°

59° = x . . . . . . . subtract 56°

Answer:

x = 59

Step-by-step explanation:

angle 115 and angle 56 + x are alternate angles and congruent, thus

56 + x = 115 ( subtract 56 from both sides )

x = 59

I already made an attempt at this question and I would just like to check my answer z = ?

Salsk061 [2.6K]

So we have the equation:

$\frac{z+9}{4}=2.1$

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

$z+9=8.4$

Then we subtract 9 on both sides to solve for z:

$z=-0.6$

Therefore the answer is z = -0.6.

Given ZW=20. Answer the questions please.

djyliett [7]

a) Corresponding angles of similar figures are congruent, so $\angle B \cong \boxed{\angle Z}$

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is $\frac{25}{10}=\boxed{5/2}$

c) Since the scale factor is 5/2,

$\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}$
