Can someone tell me the answer for this <br><br><br> I got this wrong on my first attempt ._.
dimaraw [331]

Answer:

86°

Step-by-step explanation:

This is a circle theorem question, specifically the cyclic quadrilateral theorem.

If you have a a 4-sided shape that touches the circumference of the circle with all 4 vertices, it's know as a cyclic quadrilateral.

The theorem states: "Opposite angles in a cyclic quadrilateral add up to 180°"

We want the angle at point L so we subtract the opposite angle to L (Angle J, which is 94°), so 180 - 94 = 86

The neat thing is that it's still a quadrilateral, and if you find all the remaining sides, they should add up to 360°, just like a regular square or rectangle.

Question 3 of 10
Grace [21]

The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The area of the space = 18 ft * 16 ft = 288 ft²

The cost per month is $18 per ft² per month, hence:

The cost of rent per year = $18 per ft² per month * 288 ft² * 12 month = $62,208

The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208

If the scale of a map is 2 centimeters=21 kilometers, then what is the actual distance of 14 millimeters?​
Ad libitum [116K]

Answer:

14.7 km

Step-by-step explanation:

Given:

Scale of a map is 2 cm = 21 km.

We know that, 1 cm = 10 mm

Therefore, 2 cm = 2 \times 10 = 20 mm

Therefore, the scale of the map is, 20 mm = 21 km

Now, let the actual distance be 'd' km for 14 mm.

Using proportion of the two quantities, we get:

\frac{d}{14}=\frac{21}{20}

Multiplying both sides by 14, we get:

\frac{d}{14}\times 14=\frac{21}{20}\times 14\\d=\frac{21\times 14}{20}=\frac{147}{10}=14.7\ km

Therefore, the actual distance of 14 mm is 14.7 km.
