Step-by-step explanation:

You need to find one of the following proves:

SSS (side, side, side)
SAS (side, angle, side)
ASA (angle, side, angle)

1) The firs one is mentioned - ∡MRQ = ∡NQR

2) QR is common for both triangles

3) PQ = PR -> that means triangle is equilateral and angles ∡PQR = ∡QRP

Now you now 2 angles and 1 side are the same.

Using ASA (angle, side, angle) that's prove both triangles are congruent.

Anton [14]

Answer:

37.69 (≈ 38 ft²)

Step-by-step explanation:

2πr = 30.77

r = 30.77 / (2 * 3.14) = 4.9

half of free-throw circle area: πr² / 2 = (3.14 * 4.9²) / 2 = 37.69 (≈ 38 ft²)

Simplify the following polynomial

Amiraneli [1.4K]

Answer:

-3x^4 - 13x^3 + 14x - 7

Step-by-step explanation:

(5x^4 – 9x^3 + 7x – 1) + (-8x^4 + 4x^2 – 3x + 2) - (-4x^3 + 5x - 1)(2x – 7)

simplify multiplied terms

(-4x^3 + 5x - 1)(2x – 7)

(-4x^3+10x-8)

group like terms together

(5x^4-8x^4) + (-9x^3-4x^3) + (7x-3x+10x) + (-1+2-8)

simplify grouped terms

-3x^4 - 13x^3 + 14x - 7
