Answer: the measure of the indicated angle is 100 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees. Let x represent the unknown angle in the bigger triangle. Therefore,

x + 80 + 25 = 180 degrees

x + 105 = 180

x = 180 - 105 = 75 degrees.

Let z represent the other unknown angle in the smaller triangle. Since the sum of the angles on a straight line is 180 degrees, therefore

75 + 55 + z = 180

130 +z = 180

z = 180 - 130 = 50 degrees

Let y represent the unknown angle that we are looking for. Therefore,

50 + y + 30 = 180

80 + y = 180

y = 180 - 80 = 100 degrees

When given the information below, can you conclude that Quadrilateral WXYZ is a parallelogram? Why or why not?
Masja [62]

B) No, because opposite sides are not parallel

Step-by-step explanation:

Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;

Parallel sides to be : WX // YZ   and XY // WZ

Additionally, we know parallel sides have equal gradient thus;

The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ

However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.

What is 33 and 67 in it's simplest ratio
murzikaleks [220]
To find the simplest ratio, you must find the largest number they can both be divided by (greatest common factor, or GCF). However, 67 is a prime number, meaning its only factors are 67 and 1. That means there are no GCFs here other than 1, so, the simplest ratio here would be 33 over 67, or 33/67 in computer text. easy peasy!

An online store increased the price of a shirt by 17% and charged $3 to ship the shirt to a customer. The customer paid $43 for
Fantom [35]

Answer:

Check explanation

Step-by-step explanation:

Let

x = original price

Percentage increase in price = 17%

New price = original price + Percentage increase in price

= x + 17% of x

= x + 0.17 * x

= x + 0.17x

= 1.17x

Shipping cost = $3

Total cost = $43

Total cost = New price + Shipping cost

43 = 1.17x + 3

43 - 3 = 1.17x

40 = 1.17x

x = 40 / 1.17

x = $34.188034188034

Approximately,

x = $34.2
