[tex]\color{plum}\tt2x + 7° = \underline{65} \: degrees[/tex]
Steps to derive the correct solution :The exterior angle corollary states that the measure of a triangle's exterior angle is the sum of the opposite interior angles of the exterior angle.
Which means :
∠36° + ∠x° = ∠(2x + 7)°Let us solve this equation to find the measure of the exterior angle :
[tex] =\tt 2x + 7 = 36 + x[/tex]
[tex] = \tt2x + 7 - x = 36[/tex]
[tex] =\tt x + 7 = 36[/tex]
[tex] = \tt \: x = 36 - 7[/tex]
[tex] =\tt x = 29[/tex]
Thus, the measure of ∠x = 29°Then, the measure of the exterior angle :
[tex] = \tt2 \times 29 + 7[/tex]
[tex] = \tt58 + 7[/tex]
[tex] = \tt65[/tex]
Thus, the measure of the exterior angle 2x+7 = 65°
Let us check whether or not we have found out the correct measure of each angle by placing 29 in the place of x:
[tex] = \tt2 \times 29 + 7 = 36 + 29[/tex]
[tex] =\tt 58 + 7 = 36 + 29[/tex]
[tex] = \tt65 = 65[/tex]
Since the measures match we can conclude that we have found out the correct value of each angle.
Therefore, ∠2x + 7° = 65°

Answer:
Step-by-step explanation:
Switch the x and y variables

Solve for the new y value by taking the natural log of both sides
[tex]ln|x|=y*ln(3)[/tex]
Divide both sides by the natural log of 3
[tex]\frac{\ln|x|}{\ln(3)} =y[/tex]

What is the length of AC? What is the measure of angle A? What is the measure of angle B?
Answers
Answer/Step-by-step explanation:
✔️Find AC using Pythagorean Theorem:
AC² = 25.2² - 11.3²
AC² = 507.35
AC = √507.35
AC = 22.5 (nearest tenth)
✔️Find m<A using trigonometric ratio:
Reference angle = A
Opp = 11.3
Hyp = 25.2
Sin(A) = opp/hyp
Sin(A) = 11.3/25.2
A = sin^{-1}(11.3/25.2)
A = 26.6° (nearest tenth)
✔️Find m<B using trigonometric ratio:
Reference angle = B
Adj = 11.3
Hyp = 25.2
Cos(A) = adj/hyp
Cos(A) = 11.3/25.2
A = cos^{-1}(11.3/25.2)
A = 63.4° (nearest tenth)

is about 1.9 X 10° miles long. How
should Terry write the length of the Rio
Grande in standard form on his report?
Answers
Answer:
1,900
Step-by-step explanation:
You have to do 1.9 times 10 to the power of three but first figure out the number to ten to the power of three which is 1,000. So 1,000 time 1.9 equal 1,900.
