Answer:
Statement 1. P
Reason 1. Theorem: The measure of an external angle of a triangle is equal to the sum of the measures of the remote interior angles.
Statement 2. 132 = 3x + 54
Statement 3. x = 26
False; consider as a counterexample the function <em>f</em> : ℝ→ℝ defined by
Clearly <em>f</em> approaches -3 as <em>x</em> gets closer to -2, but neither limit from either side is equal to the function's value at <em>x</em> = 2 (that is, -3 ≠ 0), so <em>f</em> is not continuous.
If u round tha to the nearest 10th it’s 4.8
One way is to first find the measure of one external angle:-
Measure 1 ext angle = 360 / 10 = 36 degrees (Note the sum of the external angles of all polygons is 360 degrees)
So the internal angle = 180 - 36 = 144
So sum of the internal angles
= 10 * 144
= 1440 degrees (answer)
Answer:
1. 7x + 2 3/5
2. 2x-6.3
3. 27t + 36b
4. 3.5a - 9.1p
5. 8(x+7)
6. 3(x+19)
7. y= -8.9
8. n = -18
Step-by-step explanation:
1. combine like terms
2. Keep change change then combine like terms
3. distribute
4. distribute
5. have 8 in common
6. have 3 in common
7. subtract 1.6 from -7.3
8. multiply both sides by -2/3
