Answer:

∠ 1 = 99°, ∠ 2 = 81°, ∠ 4 = 81°

Step-by-step explanation:

∠ 1 and ∠ 3 are vertical angles and are congruent, then

∠ 1 = 99°

∠ 1 and ∠ 2 are adjacent angles and sum to 180° , so

∠ 2 = 180° - 99° = 81°

∠ 2 and ∠ 4 are vertical angles and are congruent, so

∠ 4 = 81°

(w+9) (w+4) find the product of the equation
Pachacha [2.7K]

Answer:

w^2 + 13w + 39

Step-by-step explanation:

Multiplying Polynomials (FOIL- Firsts, Outs, Inners, Lasts)

(w+9) (w+4)          Multiply- Firsts (w*w)   Outs (w*4)   Inners (9*w)   Lasts (9*4)

w*w + w*4 + 9*w + 9*4     Multiply the FOIL

w^2 + 4w + 9w + 36          Combine like terms (same variables, numbers)

w^2 + 13w + 39

Let's solve this using unitary method ~

  • \sf3 \: seconds = 63 \:  meters

  • \sf1\: second= 63 \div 3 \:  meters

  • \sf1\: second= 21 \:  meters

  • \sf5\: seconds= 21 \times 5 \:  meters

  • \sf5\: seconds= 105 \:  meters

Therefore , the ostrich will run 105 meters in 5 seconds.
