The measure of angle 1 is 88°.

Explanation

when we draw the system of parallel lines and a transversal , we find that 92° and <2 are corresponding angles.

In a system of parallel lines intersected by a transversal, the corresponding angles will be equal.

<2=92°

< and <2 form a linear pair and their sum will be equal to 180°.

<1+<2=180°

<1+92°=180°

<1=180-92=88°

Can you explain how you would convert 4 m to millimeters?

Andrew [12]

M to millimetres is 3 steps. m > dm > cm > mm. since it is 3 steps down, the comma goes 3 places left. 4 > 0,4 > 0,04 > 0,004. so 4 m is equal to 0,004 mm

Answer:

Exact circumference is $7\frac{49}{150}km$

Approximate circumference is $7.33 km$

Step-by-step explanation:

We are given;

The diameter of a circle as $2\frac{1}{3} km$

We are required to determine the exact and approximate circumference of the circle.

We know that the circumference of the circle is given by;
Circumference = πD, where D is the diameter

Taking π as 3.14

$Circumference=3.14 (2\frac{1}{3}km)$

$=7\frac{49}{150}km$

The exact circumference of the circle is $7\frac{49}{150}km$

$7\frac{49}{150}km=7.327 km\\ = 7.33 km (nearest hundredth)$

Thus, the approximate circumference of the circle is $7.33 km$
