Answer:

This shape is a hexagon. Angles in a hexagon add to 720 degrees.

2(y) + 4(2y-20) = 720

2y + 8y-80 = 720

10y-80=720

10y=800

y=80

Let me know if this helps!

Which postulate can be used to prove that two triangles are congruent

user100 [1]

Side-Side-Side Theorem, Side-Angle-Side, Angle-Angle-Side, Angle-Side-Angle, and Hypotenuse-Leg for right triangles.

For example, for Side-Side-Side, if you prove all 3 sides of the triangle are congruent, then the triangle is congruent.

Which postulate or theorem can be used to

sveticcg [70]

Answer:

AA Similarity Postulate

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

step 1

Verify the proportion of the corresponding sides

$\frac{PS}{PQ}=\frac{PT}{PR}$

substitute

$\frac{45}{20}=\frac{36}{16}$

$2.25=2.25$ ----> is true

Corresponding sides are proportional

Triangle PQR is similar to Triangle PST

That means

Corresponding angles must be congruent

side QR is parallel side ST

and

$m\angle PQR=m\angle PST$ ----> by corresponding angles

$m\angle PRQ=m\angle PTS$ --> by corresponding angles

PQR is similar to PST by AA Similarity Postulate

A fireworks display is launched from a platform 10 feet above ground with an initial upward velocity of 70 feet per second. The

Lena [83]

Answer: A. 87 feet

Step-by-step explanation:

1. You can find the t value of the vertex of the parabola as following:

$t=-\frac{b}{2a}$

2. Substitute values:

a=-16

b=70

Then:

$t=-\frac{70}{2(-16}$

$t=2.18$

3. Substitute the vaue obtained into the equation given in the problem. Therefore, you obtain the following result:

$h=-16t^{2}+70t+10\\h=-16(2.18)^{2}+70(2.18)+10\\h=86.56$

4. To the nearest foot:

h=87 feet
