Find the measure of the missing angle

Mathematics
1 answer:
Leokris [45]2 years ago

Answer:

z = 69°

Step-by-step explanation:

The sum of all interior angles in a quadrilateral is 360°, and a right angle is worth 90°. We're given the values of the interior angles as 90, 122, 79, and z degrees.

  • We can solve this question algebraically with the equation 90 + 122 + 79 + z = 360

Step 1: Combine like terms.

  • (90+122+79)+z=360
  • z + 291 = 360

Step 2: Subtract 291 from both sides.

  • z + 291 - 291 = 360 - 291
  • z = 69

Step 3: Check if solution is correct.

  • (69) + 261=360
  • 360 = 360

Therefore, z = 69°.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Plz Help meee!!!<br><br>Factor the Trinomial<br><br>x^2+12x+27​
mojhsa [17]

Answer:

(x + 9)(x + 3)

Step-by-step explanation:

Factor 27 so that the factors, when combined, will equal 12:

x² + 12x + 27

x                9

x                3

(x + 9)(x + 3) is your answer.

Check: Use the FOIL method. Multiply the first two terms, the outside terms, the inside terms, and then the last two terms. Combine like terms:

(x + 9)(x + 3) = x² + 3x + 9x + 27 = x² + 12x + 27 (√)
