Find the angle with the smallest measure in △ VUW. Name the angle using three letters
Nimfa-mama [501]

Answer:

∠VUW

Step-by-step explanation:

A triangle is a three sided polygon with three angles. Types of triangles are obtuse, scalene, isosceles, equilateral and so on.

In triangle VUW, since VU = WU, hence it is an isosceles triangle. In an isosceles triangle, two sides of the triangle are equal.

The size of an angle depends on its opposite side, the higher the opposite side the higher the angle. Since In triangle VUW, VU = 9, WU = 9, VW = 5. Since VW is the smallest side, the angle opposite to VW is the smallest angle.

Hence the smallest angle = ∠VUW

Austin pays $2 per day for high speed internet. The equation y = 2x relates his internet charges (y) to the number of days (x) h
Alika [10]

Answer:

Option C. 2

Step-by-step explanation:

Let

x ----> the number of days

y ----> the internet charges in dollars

we have

y=2x

This is a proportional relationship between the variables x and y

The slope of the linear function is equal to the constant of proportionality k

k=m=2\frac{\$}{day}

The unit rate is the same that the slope

so

The unit rate is $2 per day

therefore

The unit rate in the equation is 2

alyssa answered 90% of her math test correctly. there were 50 questions on the test. how many questions did alyssa answer correc
marissa [1.9K]
Since she answered 90% of her quiz correct, that means if she were to answer 10 questions, 9 would be correct. Lucky for us, 50 is a multiple of 10. If you multiply 10 by 5, you'd get 50. You would also need to multiply 9 by 5 as well. When you do this you'd get

45/50 correct. (divided them to make sure you get .90 if so, I'm right :)
