Answer:

2x + x + 63 = 180 to find x.

m<1 = 78 degrees

m<2 = 102 degrees

Step-by-step explanation:

Combine like terms: 3x + 63 = 180

Subtraction: 3x = 117

Division: 3x/3 = 117/3

Final Answer: x = 39

m<1 = 2(39) = 78 degrees

m<2 = (39 + 63) = 102 degrees

Check work: 102 + 78 = 180

(180 is the measure of a straight line such as the one represented here)

A triangle is shown.
aleksklad [387]

Using the Pythagorean Theorem, it is found that the unknown side length of the triangle is of 7.9 cm.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

Researching this problem on the internet, we have that:

  • The unknown side length is of a leg of x.
  • The other leg is of 9 cm.
  • The hypotenuse is of 12 cm.

Hence:

x² + 9² = 12²

x = sqrt(12² - 9²)

x = 7.9 cm.

The unknown side length of the triangle is of 7.9 cm.
