Answer:
Step-by-step explanation:
<u>Question 1</u>
Two isosceles triangles with repeat 72°.
- x = 180° - 2*72°
- x = 180° - 144°
- x = 36°
<u>Question 2</u>
Isosceles triangle with repeat x/2 angle and a x angle.
- 2(x/2) + x = 180°
- 2x = 180°
- x = 90°
Answer:
![v\sqrt[28]{v^{13}}](https://tex.z-dn.net/?f=v%5Csqrt%5B28%5D%7Bv%5E%7B13%7D%7D)
Step-by-step explanation:
The exponent rules that apply are ...
![(a^b)(a^c)=a^{b+c}\\\\a^{\frac{b}{c}}=\sqrt[c]{a^b}](https://tex.z-dn.net/?f=%28a%5Eb%29%28a%5Ec%29%3Da%5E%7Bb%2Bc%7D%5C%5C%5C%5Ca%5E%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%5Csqrt%5Bc%5D%7Ba%5Eb%7D)
Using these rules for your product, we have ...
![v^{\frac{3}{4}}\times v^{\frac{5}{7}}=v^{\frac{3}{4}+\frac{5}{7}}\\\\=v^{\frac{41}{28}}=v\cdot v^{\frac{13}{28}}=v\sqrt[28]{v^{13}}](https://tex.z-dn.net/?f=v%5E%7B%5Cfrac%7B3%7D%7B4%7D%7D%5Ctimes%20v%5E%7B%5Cfrac%7B5%7D%7B7%7D%7D%3Dv%5E%7B%5Cfrac%7B3%7D%7B4%7D%2B%5Cfrac%7B5%7D%7B7%7D%7D%5C%5C%5C%5C%3Dv%5E%7B%5Cfrac%7B41%7D%7B28%7D%7D%3Dv%5Ccdot%20v%5E%7B%5Cfrac%7B13%7D%7B28%7D%7D%3Dv%5Csqrt%5B28%5D%7Bv%5E%7B13%7D%7D)
Draw a right triangle (attachment below):
Length of the vertical line = 6 units
Length of horizontal line = 8 units
a^2 + b^2 = c^2
6^2 + 8^2 = 100
Square root of 100 = 10
The distance between the two points is 10 units.
Answer:
The answer to your question is: -9y³ - 3y² + 5y - 9
Step-by-step explanation:
( y² - 3y³ - 2 + 5y ) - (7 + 8y² - 4y² + 6y³)
y² - 3y³ - 2 + 5y - 7 - 8y² + 4y² - 6y³
Like terms -3y³ - 6y³ + y² - 8y² + 4y² + 5y - 2 - 7
-9y³ - 3y² + 5y - 9
