PQR has two known interior angles of 34°, and 80°. △RST has two known interior angles of 24°, and 90°. What can be determined ab
Shalnov [3]

Answer:

△PQR and △RST are not similar.

Step-by-step explanation:

In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is

180-34-80=66

In triangle △RST, two known interior angles are 24° and 90°.

180-24-90=66

Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.

Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.

Please solve this for me!
tatuchka [14]

Step-by-step explanation:

To find the slope between two given points you use the equation:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

(8,10) are (x_{1},y_{1})

(16,24) are (x_{2},y_{2})

After that you just plug in:

m=\frac{24-10}{16-8}

m=\frac{14}{8}

Simplify:

<h2><u><em></em></u>m= \frac{7}{4}<u><em></em></u></h2>

Answer:

The slope is \frac{7}{4} for #1

Dr.Casey has a cylindrical beaker he fills with about 113 cubic inches of hydrochloric acid. The hydrochloric avid has a height
GREYUIT [131]

Answer: the diameter of the hydrochloric acid in Casey's container is 6 inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylindrical beaker.

h represents the height of the cylindrical beaker.

π is a constant whose value is 3.14

From the information given,

Volume cylindrical beaker = 113 cubic inches.

Height = 4 inches

Therefore,

113 = 3.14 × r² × 4

113 = 12.56r²

r² = 113/12.56 = 8.9968

r = √8.9968

r = 3

Diameter = 2 × radius

Diameter = 2 × 3 = 6 inches
