What is the measure of Angle A?

Marysya12 [62]

Answer:

136

Step-by-step explanation:

The sum of interior angles of a polygon is (n-2)x180 where n is the no. of sides. Here n=5 Therefore sum of int. angles = (3-2)x180= 3x180=540.

Sum of all given angles =404.

Remaining angle= 540-404=136

What is the solution to the system of equations? y = 2x – 3.5 x – 2y = –14 (–7, 3.5) (3.5, –7) (7, 10.5) (10.5, 7)

Mandarinka [93]

y = 2x-3.5 ----->1

x-2y=-14. ----->2

1 into 2

x-2(2x-3.5)=-14

x-4x+7=-14

-3x=-14-7

-3x=-21

x=-21/-3

x=7 --- -->3

3 into 1

y = 2x-3.5

y=2(7)-3.5

y=10.5

What is the value of es026-1.jpg?

Kay [80]

Answer:

Value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1

Step-by-step explanation:

To find the value of $[(\frac{2}{3})^0]^{-3}$

Using exponents power rule:

$(a^m)^n = a^{mn}$

then;

$(\frac{2}{3})^{0 \cdot (-3)}$

Simplify:

$(\frac{2}{3})^{0}$

By Zero exponent rule: Anything raised to the power 0 is 1. i.e,

$a^0 = 1$

then;

$(\frac{2}{3})^{0}$ = 1

Therefore, the value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1
