Answer:

x = 129°

y = 82°

Step-by-step explanation:

x is supplementary to the angle corresponding to 51°, so is supplementary to 51°.

x = 180° -51° = 129°

y is an alternate exterior angle to the unmarked angle between 47° and 51°, hence congruent to that angle. Its measure is ...

y = 180° -47° -51° = 82°

Answer:

x = 129

y = 82

Step-by-step explanation:

x + 51 = 180

x = 180 - 51

x = 129

y + 51 + 47 = 180

y = 98 - 180

y = 82

You are making a poster to support your friend for homecoming. Your original photo is 4 inches by 6 inches. You want the photo o

Lorico [155]

Answer:

Step-by-step explanation:

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.

First of all we will convert dimensions of poster from feet to inches.

$3\text{ feet}=3\times 12 \text{ inches}=36\text{ inches}$

$4\frac{1}{2}\text{ feet}=4.5\times 12 \text{ inches}=54\text{ inches}$

Now let us compare sides of our original photo with corresponding sides of poster.

$\frac{36}{4} =9$

Now let us compare the second pair of corresponding sides.

$\frac{54}{6} =9$

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.

Two parallel lines are crossed by a transversal. What is the value of h? h = 60 h = 80 h = 100 h = 120

I added the diagram of the question.

Answer:
h = 60°

Explanation:
We are given that lines k and l are parallel lines.
This means that angles 120° and h are supplementary angles.
This means that their measures add up to 180°

Therefore:
180° = 120° + h
h = 180° - 120°
h = 60°

Hope this helps :)
