seraphim [82]

Answer:

Option A.) is correct $\triangle XYZ \sim \triangle WVZ$ by AA similarity. There are two angles that are congruent given by $\angle ZXY = \angle ZWV \hspace{0.2cm} and\hspace{0.2cm} \angle ZYX = \angle ZVW$ .

This is because both pairs represent alternate interior angles formed by lines intersecting two parallel lines.

Step-by-step explanation:

From the given figure we can say that

Tanner made his aunt a garden. The width is 9 4/5 ft and the length is 5 3/4 ft. What is the area of

ratelena [41]

Answer:

56.35 ft^2, or 56 7/20 ft^2

Step-by-step explanation:

One way of doing this problem quickly is to convert both measurements into improper fractions before multiplying them:

9 4/5 = 49/5 and 5 3/4 = 23/4.

Then the area of the garden is 49/5 times 23/4, or 1127/20 ft^2, or

56.35 ft^2, or 56 7/20 ft^2.

Find the value of x then classify the triangle by its angles

Neporo4naja [7]

Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
