Answer:

x = 120

Step-by-step explanation:

An equilateral triangle has 3 equal angles

The sum of the angles is 180

180/3 = 60

x + 60 = 180 since they form a straight line

x = 180-60

x = 120

Use grouping symbols and at least one exponent to write a numerical expression that has a value of 80.

Kaylis [27]

To group an expression, means that the factors of the expression are to be separated in (), [] or {}.

An expression with a value of 80 is: $2^2 \times ( [2 + 2] \times [3 + 2] )$

The number is given as:

$80$

Factorize

$80 = 2 \times 40$

Factorize 40

$80 = 2 \times 2 \times 20$

Express $2 \times 2$ as an exponent

$80 = 2^2 \times 20$

Express 20 as 4 x 5

$80 = 2^2 \times ( 4 \times 5)$

Express 5 as 3 + 2

$80 = 2^2 \times ( 4 \times [3 + 2] )$

Express 4 as 2 + 2

$80 = 2^2 \times ( [2 + 2] \times [3 + 2] )$

Hence, the above expression has a numerical value of 80

A circle has a radius of 6cm . find the length s of the arc intercepted by a central angle of 169° .

Igoryamba

The circumference of the circle is = 2 x pi x 6 = 37.7cm

To find the arc = 360 divided by 169 = 2.13

The arc = 37.7 divided by 2.13 = 17.69 cm
