Answer:

135°

Step-by-step explanation:

That triangle in the corner is an right angle isosceles triangle as that line the midpoint of both sides :

the base angle of this triangle (x) will be :

180 = 90 + 2x

90 = 2x

x= 45

Angles on a straight line add up to 180. So to work out a :

180 = 45 + a

135 = a

5 no mater what on first hour so, then on the second hour the 1.75 rate kicks in so therefor when x=1, then y=5 so y=5+0 times 1.75
so y=5+1.75 times (x-1)
the naswe ris
y=1.75(x-1)+5 or d

The diameter of a circle is 8 centimeters. A central angle of the circle of the circle intercepts an arc of 12 centimeters. What

Studentka2010 [4]

Answer:

The measure of the angle is $3\ radians$

Step-by-step explanation:

we know that

The formula to calculate the arc length of a circle is equal to

$L=r\theta$

where

r is the radius of the circle

$\theta$ is the measure of the angle in radians

In this problem we have

$L=12\ cm, r=8/2=4\ cm$

substitute in the formula and solve for $\theta$

$12=4\theta$

$\theta=12/4$

$\theta=3\ radians$

The scale from a map to actual distance is 2.5 cm to 620 mi. The distance on the map between Chicago and Boston is about 3.5 cm.

Answer: 868 miles

Step-by-step explanation:

Given: The scale from a map to actual distance is 2.5 cm to 620 miles.

i.e. 1 cm on map = $\dfrac{620}{2.5}\text{ miles}=248 \text{ miles}$

If the distance on the map between Chicago and Boston is about 3.5 cm.

Then, the actual distance between them = $3.5\times 248 \text{ miles}=868 \text{ miles}$

Hence, the approximate distance between Chicago and Boston = 868 miles.
