Answer:

36°
90°

Step-by-step explanation:

Question 1

Two isosceles triangles with repeat 72°.

x = 180° - 2*72°
x = 180° - 144°
x = 36°

Question 2

Isosceles triangle with repeat x/2 angle and a x angle.

2(x/2) + x = 180°
2x = 180°
x = 90°

Rational exponents: product rule simplify v^3/4 multiply v^5/7

marusya05 [52]

Answer:

$v\sqrt[28]{v^{13}}$

Step-by-step explanation:

The exponent rules that apply are ...

$(a^b)(a^c)=a^{b+c}\\\\a^{\frac{b}{c}}=\sqrt[c]{a^b}$

Using these rules for your product, we have ...

$v^{\frac{3}{4}}\times v^{\frac{5}{7}}=v^{\frac{3}{4}+\frac{5}{7}}\\\\=v^{\frac{41}{28}}=v\cdot v^{\frac{13}{28}}=v\sqrt[28]{v^{13}}$

Use the pythagorean theorem to find the distance between the points (4,3) and (-4,-3)

maxonik [38]

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.

(Y^2-3y^3-2+5y)-(7+8y^2-4y^2+6y^3

miv72 [106K]

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
