President-elect Donald Trump's administration begins taking shape, thousands poured onto the streets of a divided nation again Saturday to express their frustration at the stunning election
While largely peaceful, the protests have resulted in blocked highways and bridges, arrests during clashes with police and the early Saturday shooting of a man at a march in Portland, Oregon. Hope that helps you
Answer:
6 dresses
Step-by-step explanation:
Given: sales price is $d
Regular price is 3 times of sales price
Janine has money to buy 2 dresses at regular price.
Now, finding the number of dresses Janine can buy at the sales price, if sale price is d
Regular price=
Janine has total money= (∵ regular price is 3d)
∴ Number of dresses bought by Janine=
⇒ Number of dresses bought by Janine=
∴ Number of dresses bought by Janine is 6.

The measure of each angles a,b and c are 32°, 74° and 74° respectively.
What is triangle?
Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one. The symbol for an ΔABC triangle is A, B, and C.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.
Let angle b be x
Therefore angle c will also be x [as given b and c are equal] and angle a will be x - 42°.
Now as we know that the sum of the measures of the angles of a triangle is 180° therefore,
x + x + x - 42° = 180°
=> 3x = 222°
=> x = 74° which is angle b and c
and angle a is (74 - 42)° =32°
