If two angles from a linear pair and the m<1=2x+20 and m<2=48x find the measure of each angle
il63 [147K]

The measures of two angles in a linear pair add to 180 deg.

m<1 + m<2 = 180

2x + 20 + 48x = 180

50x + 20 = 180

50x = 160

x = 3.2

m<1 = 2x + 20 = 2(3.2) + 20 = 6.4 + 20 = 26.4

m<2 = 48x = 48(3.2) = 153.6

Answer: m<1 = 26.4 deg; m<2 = 153.6 deg

1. A theater group bought supplies to construct the set of a play. Lumber cost $145.86, paint cost $52.91, and hardware cost $17
Pani-rosa [81]
(a) 145.86 + 52.91 + 17.63 = 216.4
(b) 17.63/216.4 × 100% = 8.15%
(c) 52.91 + 17.63 / 216.4 × 100% = 32.60%

If c and d are supplementary, and the measure of d is 45 what is the measure of c?
dsp73
The definition of supplementary is that the angles add to 180°. Hence, <em>c + d = 180; c + 45 = 180  </em>by substitution and finally ∡c = 135°.

If m∠F = 90° and m∠G = 70°, then ∠F and ∠G are not supplementary.
miss Akunina [59]

a) Proof by contradiction is different from traditional proof as it accepts a single example showing that a statement is false, instead of having the need to derive a general relationship for all input values.

b) The statement is true by contradiction as the sum of the measures is of 160º, and not 180º.

<h3>What are supplementary angles?</h3>

Two angles are called supplementary angles if the sum of their measures has a value of 180º.

The measures of the angles in this problem are given as follows:

  • m∠F = 90°.
  • m∠G = 70°.

Then the sum of the measures of this angles is given as follows:

90 + 70 = 160º.

Which is a different sum of 160º, confirming the statement that the angles are not supplementary by contradiction.

A similar problem, involving proof by contradiction and supplementary angles, is presented at brainly.com/question/28889480
