All of the angles should always add up to 360 degrees.

you already have RKG being 87, and you are given that AKG is 133, the sum of these two angles minus 360 degrees will give you your answer which is 140 degrees

An isosceles triangle has base angles that each measure 42 degrees.Which equation can be used to find z, the measure of the thir

gavmur [86]

Answer:

z+42+42=180

Step-by-step explanation:

Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:

z+42+42=180

If you need to find z, it is 96.

Check: 96+42+42=180

Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $

arsen [322]

Cost of 2 pounds of almonds = $ 21.98

So, cost of 1 pound will be = $\frac{21.98}{2} = 10.99$

Cost of 3 pounds of dried apricots = $26.25

So, cost of 1 pound will be = $\frac{26.25}{3} = 8.75$

So, comparing the two costs, the cost of 1 pound of dried apricot is less than 1 pound of almonds by $2.24

The following set of coordinates most specifically represents which figure? (−5, 6), (−1, 8), (3, 6), (−1, 4) (6 points) Paralle

Vladimir [108]

Answer:

Rhombus

Step-by-step explanation:

The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).

We use the distance formula to find the length of AB.

$|AB|=\sqrt{(-1--5)^2+(8-6)^2}$

$|AB|=\sqrt{16+4}$

$|AB|=\sqrt{20}$

The length of AD is

$|AD|=\sqrt{(-1--5)^2+(6-4)^2}$

$|AD|=\sqrt{16+4}$

$|AD|=\sqrt{20}$

The length of BC is:

$|BC|=\sqrt{(-1-3)^2+(8-6)^2}$

$|BC|=\sqrt{16+4}$

$|BC|=\sqrt{20}$

The length of CD is

$|CD|=\sqrt{(-1-3)^2+(6-4)^2}$

$|CD|=\sqrt{16+4}$

$|CD|=\sqrt{20}$

Since all sides are congruent the quadrilateral could be a rhombus or a square.

Slope of AB $=\frac{8-6}{-1--5}=\frac{1}{2}$

Slope of BC $=\frac{8-6}{-1-3}=-\frac{1}{2}$

Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus
