30-10x and 10(3-x) equivalent or not?

Mathematics
1 answer:
BARSIC [14]3 years ago
3 0

Answer:

no

Step-by-step explanation: You can use variables to find that out. PEMDAS works too (parenthesis, exponents, multiplication, division, addition, subtraction). Put a random number for x and then you can see that it is not equivalent. Example: 30 - 10x7 = 40 but 10 (30-70) = -400

arlik [135]

Answer:

  • 48°
  • ∠Y ≅ ∠X

Step-by-step explanation:

<h3>Question 1</h3>

<u>Prove that The two triangles are congruent</u>

  • ∠ABD ≅ ∠BDC - given
  • BD ≅ DB - reflexive property
  • ∠ADB ≅ ∠CBD - given
  • ΔABD ≅ ΔCDB - ASA postulate

<u>Find the measure of angle C</u>

  • ∠A ≅ ∠C - Corresponding  parts of congruent triangles
  • m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>

<u>Given </u>

  • ΔXYZ with XZ ≅ YZ

Opposite angles are corresponding to the sides.

Therefore the angles opposite to congruent sides are also congruent:

  • ∠Y ≅ ∠X
